Tummy time
In just four weeks, your son has grown by almost 2 inches (5 cm) and has gained about 2 lbs (1 kg) [1]. Though he mostly sleeps, he’s still learning so many skills. For example, he’s learned to smile in response to certain reflexes.
Newborns generally live on reflexes: sucking, searching (for mama's breast), the Moro reflex (flinching and stretching their arms at loud sounds). Many parents love the grasping reflex: if you put your finger in the palm of the baby, he will squeeze it very tightly. This creates an impression of awareness and a sense of intimacy, even though it is a reflex.
Your son is developing at an amazing speed and mastering new skills. And during this time of growth, it’s great to give him tummy time. Put him on a blanket on the floor or right on your stomach. He will try to raise and turn his head, leaning on his hands.
Tummy time has many benefits. First, it will strengthen the muscles of his shoulders and neck. Secondly, it will give him a new vantage point, because most often he looks at the ceiling from a lying position. Laying out on the stomach also helps to prevent positional skull deformity, which is possible if newborns always sleep in the same position [2]. Always stay close at hand during tummy time — at this age, your son can not yet hold up his head on his own, which can be very frustrating for your little one.
