My son is 4 months and he is so active not sure if it's the age a baby thing or he is just hyper. I'm a first time mom. He moves so much roll over constantly kicking like if he was jumping on the bed but kicking wise in his crib he ends up all over the crib. He screams or talks very loud while he's doing it. He looks like a ball of energy. Not sure if it's all babies or what.
