My son is 6months in a week and for the past few nights around 3am he has stated waking, not crying just fidgity. He's slept well since being a newborn, he only woke at 5am for a feed. N at 4 month he slept through. He is teething but we usually get the crying n pain around 7pm n like I said he's not waking crying, just fidgity. His eyes r still closed n he drops back off then he's awake again 15/20 mins later, this goes on til 7am. He's warm enough, he's feed plenty, he learned rolling both ways by 5month, so I'm not sure its regression or teething, nothing has changed in the room or his crib or in the house. Me and hubby r very confused, sleep deprived n more importantly so is baby, help???
