Motor Development: From Holding the Head Up to Running

In your baby's development, movement is perhaps the most concrete, most visible part. Your tiny baby, who could barely hold their head up one day, months later sits, then crawls, stands, and before you know it starts running around the house. Every step of this journey thrills you, and sometimes makes you wonder, "Is this happening too late?" In this chapter, we'll explain in a warm way the order in which your child's movement skills develop, what lies beneath each step, and when it makes sense to see a doctor. I'd like you to know from the start: movement development is not just about muscles getting stronger; it's actually one of the earliest and most reliable signs that the brain and nervous system are maturing in a healthy way. That's exactly why watching your child's movements gives you and your doctor very valuable information.

Two simple rules

Movement development doesn't proceed randomly; it follows two basic rules. The first is progress from head to toe: control is gained first in the head, then the trunk, and last in the legs. That's why your baby learns to sit before walking, and to hold their head up before sitting. The second is progress from the center outward: control develops first in the joints near the middle of the body (shoulders, hips), then in the joints at the ends (wrists, fingers). That's why your baby makes the broad sweeping movement of the whole arm long before the fine grasp with the fingertips.

A third pattern accompanies these two: your baby first responds with the whole body all at once, and over time becomes able to make selective, fine movements by isolating a single joint or finger. At the start everything is large and lumped together; gradually it becomes finer and more purposeful. Behind all this progress is the maturing of the nerve pathways in the brain.

Head control is the foundation of it all

The lead role in this journey belongs to head control, and it's most clearly seen in the first three months. When your newborn lies on their back, they can't hold their head in the middle; it's usually turned to one side. But when lying on the tummy, they can lift their head briefly and turn it to the side to breathe. Toward the end of the second month, they lift their head to about 45 degrees while on their tummy; in the third month they raise it even higher and can prop up on their forearms.

When you take your baby by the hands and gently pull them up to a sitting position, in the first weeks you'll see the head lag behind; this is called head lag (the head not following the body when pulled up). This lag should clearly lessen toward the third month, and by the fourth month the head should be able to stay upright in line with the body. The head becoming steady is a sign not only of the neck muscles but also of the brain's balance centers maturing.

The hands explore the world

Once the head is steady, the doors of the visual world open. With a steady head, the eyes can focus on an object and follow it. Around the fourth month, your baby brings their hands together over the chest, clasps them, and takes them to the mouth. In this period it's very natural for them to gaze at their own hands for a long time; they're exploring their own body and building a link between eye and hand.

Hand skill also follows the center-outward rule; it starts at the shoulder and gets finer toward the fingertips. Grasping matures step by step:

• Around 4–5 months, the first voluntary grasps are made with the little-finger side of the hand and the palm, without the thumb joining in.
• Around 6–7 months, grasping shifts toward the thumb side; the object is held in the palm and fingers.
• Around 8–9 months, they can hold an object between the thumb and the side of the other fingers, without the palm coming into play.
• Around 9–10 months, a not-yet-mature grasp appears between the thumb and the forefinger.
• Around 10–12 months, they can delicately pick up a small object, such as a raisin, with the tips of the thumb and forefinger. This is an important turning point in fine hand skill.

Interestingly, releasing an object in a controlled way is learned later than grasping; your baby manages to let go of an object on purpose around 9–12 months, and to use two objects together (for example, dropping a block into a box) around 12–15 months.

Rolling, sitting, and the trunk growing stronger

Trunk control and rolling are your baby's first step toward the freedom of moving from place to place. Here a distinction needs to be made. Early rolling, sometimes seen even in the second month, is usually not voluntary; when the baby turns the head, the whole body rolls like a log. True, voluntary rolling requires a more mature pattern where the shoulder and hip areas move independently of each other, and it's usually gained around 5–6 months. Babies usually roll from tummy to back first, because it's easier; rolling from back to tummy comes a little later.

Sitting balance is one of the most important turning points; because once a baby can sit, their hands are freed from supporting the body and become free to explore the world. Around the sixth month, when your baby is placed sitting with support, they can hold the trunk upright briefly, but put their hands out in front to keep balance; this is called the tripod position. Around 7–8 months, they sit independently, lifting their hands off the floor. This isn't just muscle strength; your baby has now learned to catch themselves when balance is lost and to throw their hands out to the side to avoid toppling over. Remember: it's hard to make fine hand movements on a wobbly trunk; that's why a steady trunk is also the foundation for hand skills.

There are many ways to crawl

A sitting baby's next step is usually crawling; but crawling varies more from child to child than any of the movement milestones. Classic cross-crawling, where one arm and the opposite leg go forward together, is a lovely rehearsal of the cooperation between the two halves of the brain. That said, every child may have their own solution: some scoot on their tummy, some slide on their bottom, some move by rolling, and some skip crawling entirely and go straight to standing. If your child's muscles and other areas of development are normal, these different routes are not a problem. In fact, a considerable number of children walk without ever crawling on all fours; this alone is not a cause for concern.

What really matters here are two things: the two sides of the movement being balanced, and your child's desire to explore their surroundings. Constantly dragging one leg while crawling, using only the arms and leaving the legs still, or always using the same side, however, is a sign that deserves attention.

Standing up and the first steps

Around 9–10 months, your baby pulls up to stand by holding onto something; this shows the leg muscles have now reached the strength to work against gravity. There's a common, endearing situation in this period: the baby can stand up but can't yet manage to sit back down, because coming down in a controlled way is harder than going up.

Next comes walking sideways while holding onto furniture; we call this cruising, and it's usually seen around 10–12 months. While cruising, your baby puts their weight on one leg and opens the other out to the side. This strengthens the balance muscles needed for the independent walking to come; it's almost like training to stand on one foot.

The first independent steps we look for usually come between 12 and 15 months. A new walker's gait is very different from an adult's. The feet are apart, the knees slightly bent and turned outward; this is to make balancing easier. The arms are held up, at shoulder level; this is called high guard and serves to protect against a possible fall. In this early period the heel doesn't touch the ground; the child places the foot flat or uses the toes. The steps are short and they fall often; in fact, every step is a controlled fall, and these falls are normal. Because the fat pads on the sole of the foot haven't melted away yet, the feet may look flat; this is a temporary and natural situation. In this period, having your child walk barefoot as much as possible helps develop their balance.

Walking matures over the years. Around 18 months, the arms come down and start to swing while walking; the base of support narrows and the legs come closer together. Around age 3, a clear heel strike appears. A smooth, efficient adult-like gait, however, only fully settles in around age 7.

Running and more advanced skills

A child who has learned to walk gradually becomes faster and more coordinated. Running is different from walking; because when running, both feet leave the ground for a moment. Children usually start to run between 18 and 24 months, but at first they struggle to stop and change direction. When climbing stairs, they first bring both feet together on each step; climbing by alternating feet comes around age 3, and coming down the same way around age 4. The time they can stand on one foot increases with age: a moment at age 3, a few seconds at age 4, about 8–10 seconds at age 5. Skills like jumping, hopping, and kicking a ball also mature in this period.

Every child has their own pace

In movement development, the difference in pace between children is wide and largely normal. Whether your baby rolled over at the fifth month or the seventh is not, on its own, decisive. The two things that really shouldn't vary are: the order in which skills are gained, and the quality of the movement. In other words, the steps coming in the right order and the movements being balanced, smooth, and varied matter more than pure timing. Let's also briefly explain the idea of low muscle tone: in some babies the muscles may be looser than expected (a floppy baby), and in others too stiff; both extremes call for a doctor's evaluation.

When to see a doctor

The situations below are good reasons to have your child seen by a doctor. These are not meant to frighten you, but to help you find the right guidance at the right time. Noticing early is always an advantage.

• A clear delay in a movement milestone: for example, no head control at 4 months, not being able to sit without support at 9 months, and especially still not walking at 18 months.
• The order being disrupted: for example, trying to sit before holding the head up.
• A clear difference between the two sides of the body: using one arm or leg much less, dragging one leg while crawling.
• Clearly preferring one hand before 18 months (and in some cases even earlier). Choosing a hand early is not a strength but a sign that deserves attention.
• After the third month, constantly keeping the hand in a fist, constantly standing on tiptoe, or standing with the legs crossed (scissoring).
• Clear low muscle tone (a "floppy baby") or increasing stiffness.
• A decline in the quality of movements: little variety, monotonous and non-fluid movements.

The situation that deserves the most attention: going backward

The most important of all the signs is going backward; that is, the loss of a skill previously gained. A walking child starting to fall, a sitting baby toppling over, or no longer being able to do things they used to do with their hands is never normal. In such a case, rather than saying "let's wait and see," you need to see a doctor without losing time. Acting early truly makes a difference here.

Why noticing early is so valuable

The real purpose of recognizing motor problems early is early help. In the first two years of life, the brain is at its most open and most flexible to experience and regular practice. That's why time is precious; support started early can make a big difference for your child's later skills. Supports like physiotherapy and occupational therapy are applied with methods that put the child's active participation and daily-life skills first. Most importantly, the success of this process depends largely on the family's involvement and simple programs that can be done at home. On this journey, you are your child's closest supporter.

Finally, remember this: movement is only one part of your child's whole development. A problem in motor development can often be intertwined with language, thinking, and social development; that's why these areas should be watched together. Even so, movement holds a very special place because it gives the earliest and most concrete clues about the health of the nervous system.

• Movement development proceeds from head to toe and from the center outward; holding the head up, sitting, crawling, standing, and walking follow a certain order.
• Every child has their own pace; differences in timing are wide and mostly normal.
• What really matters is that the steps come in the right order and that the movements are balanced, smooth, and varied.
• See a doctor for a clear delay, a difference between the two sides, an early hand preference, constant tiptoe walking, or not walking at 18 months.
• The loss of a skill already gained (going backward) is the most important warning; see a doctor without losing time.
