Does anyone else's newborn wiggle so much in their sleep they move themselves sideways? I lay Rocky in his basinet straight and he moves so much he's sideways in the bed in an hour. His basinet mattress is propped up some because his acid reflux but it's not enough to slide him downwards let alone sideways. Rocky's always been very active even inside the womb so I guess he's just gonna move around a lot in his sleep.
