Your Baby's Movements
It is common for very premature babies to move very little, and when they do, it is in a "jerky" or "startled" fashion. This happens because their reflexes are not fully developed and they have little control over their muscles.
Since these babies also have weak muscles, you will have to look closely for signs of increasing strength and ability. You may see the baby moving or bending an arm or a leg.
You may also see a sucking response if you put your finger near the baby's mouth. As he sleeps, eats, and gains weight, his body shape and skin will begin to look more like that of older babies.
