Movement Development in Babies: Chest, Leg, and Arm Raising

As babies gain more motor control and begin to interact with caretakers and their environment, the reflexes they had immediately after birth start to fade.

Infants have a hard time raising their heads. They will be able to lift their heads while lying on their bellies and eventually support themselves with their arms as their neck and upper body strength increases. When they arrive, they’ll lift their heads high and scan the area.

Additionally, you might see your infant extending and kicking its legs. By preparing the legs through this motion, your baby will be better able to roll over by the time he or she is six months old. But take care: Babies can roll over at any age, so it’s crucial never to leave a child alone on a bed, changing table, or any other high surface.

Although babies instinctively grasp from birth, throughout the first three months of life they start to open and close their hands and start moving them to their mouths. When not interested, your infant may be able to drop a rattle or other item that is placed in the hand.

As your child learns to follow a moving item with their eyes, their vision also starts to get better. then observe as your infant tries to swing at toys with their arms.

Here are the three main motor movements you should watch out for your kids: chest, arm, and leg raising movements.

Chest Raising (Tummy Time)


Although babies prefer to move at their own pace, parents regularly ask us what to watch for when working with them. Here are some broad signs that we watch for while newborns are doing tummy time, whether it is on the floor, a baby pillow, or the chest of a family member.

Typically, when a baby first leaves the hospital or birthing facility and returns home, it is both safe and advised that they begin stomach time. A newborn should be able to turn their head from side to side by lifting it off the floor and turning it by the time they are one month old.

A baby should be able to maintain their elbows behind their shoulders with their arms bent and slightly away from their torso between the ages of one and two months. A newborn should be able to lift their head to a 45-degree angle by the end of the second month. A baby should occasionally push with their forearms and slightly lift their chest off the ground between the ages of 2 and 3 months, and they should start rolling from their belly to their back. A newborn should be able to keep their elbows in line with their shoulders by the time they are 3 months old, and by the time they are 3 months old, they should be able to lift their heads 90 degrees.

Leg Raising Movement

A baby’s leg muscles get stronger and their leg movements get smoother as the weeks pass, helping to get them ready for rolling over and sitting. By three months of age, the majority of infants can support some of their weight when held up in a standing position on a flat surface with their legs. By 4 to 6 months, those leg movements become more controlled; parents may notice that their kid kicks when they’re happy or delighted. The ability to kick deliberately at a toy or other target is the next stage of leg development. Your infant may accidentally kick at objects for the first few times, but with experience they will learn to kick at things on purpose.

It could be difficult to put your baby’s onesies on or buckle them into a car seat because of all the leg-raising and kicking, but it’s comforting to know that it’s a vital step in the right direction, so to speak.

Arm Raising Movement

Your infant will lift their arms in the shape of a U if you lay them on their back. This shows that your child is utilizing their arms symmetrically, which is an extremely significant achievement. It indicates that your child will soon be able to work as a team to complete a task.

While still rather rounded, your baby’s back may begin to straighten up if you hold them in a sitting position. They might only be able to maintain this stance for a little period of time.

This month, your baby’s grip reflex has continued to deteriorate. Your infant will begin to grip objects willingly as soon as the grasp reflex goes away. Their fingers will open if you try to offer them something to hold. They will attempt to bring the item to their lips if they can hold it.

The coordination of your baby’s arms and hands will keep getting better and more purposeful. Their hands are largely open, and their grip reflex has vanished. They will open their hand and attempt to hold the item between their palm and fingers if you offer it to them. They will nearly always drop the thing shortly after grabbing it since they have not yet mastered using their thumb.


Aside from growing bigger and bigger each day, your child’s movement indicates so much importance about their development. You should know what it means. Keep in mind that every baby may have somewhat different movements. It’s unlikely that your kid has a developmental delay or some other issue if she doesn’t master her motions at the same rate as others.
