Infant Motor Skills: Signs Your Baby Is Developing Well

How can I tell if an infant’s motor skills are developing okay?

Motor development is easier to gauge when you look for steady progress over time, not perfection on a single day. Most infants follow the same general sequence—gaining head control, learning to roll, sitting with support, then independently, and eventually crawling, pulling to stand, and cruising. Your baby may spend more time on one step and then suddenly surge forward, which can still be normal.

What “on track” often looks like

Healthy motor development typically shows up as improving control, strength, and coordination. You might notice your baby lifting their head higher during tummy time, bringing hands to mouth, reaching and swiping for toys, or pushing up on forearms. Later, you may see smoother rolling, better balance while sitting, and more purposeful movements like transferring a toy from one hand to the other.

Watch for symmetry and comfort

Many babies have preferences, but consistently using only one side, keeping one hand fisted most of the time, or looking uncomfortable with movement can be worth noting. Also watch how your baby responds to being placed in different positions—on their back, tummy, or supported sitting. A baby who gradually tolerates and explores these positions is generally building skills appropriately.

When to check in with your pediatrician

Consider reaching out if your baby seems unusually floppy or stiff, doesn’t improve head control over time, rarely moves arms or legs, or loses skills they previously had. Premature babies may meet milestones later based on their adjusted age, so timing should be interpreted with that in mind. If something feels “off,” it’s reasonable to ask early—quick reassurance or early support can make a big difference.

FAQ

What are early signs of developmental delays in babies?

Early signs can include very limited movement, persistent stiffness or floppiness, poor head control that doesn’t improve, or losing skills they already gained. If you notice these, contact your pediatrician for an evaluation.
