A member asked:

My baby is 4 months old and moves a lot when sleeping, is this normal and if so when will it stop?

Don't expect it: Random movement of the arms and legs in both the waking and sleeping periods are expression of a normal nervous system.The brain sends out random messages to the motor nerves to flex or extend to preserve muscle mass and tone.Without these events, the muscles would weaken like yours would if you were placed in a cast or splint.
