Our little use to be a great sleeper with only 1 or 2 feeds a night but the last week she is waking every hour. One of the wake up I do change her nappy and feed her but the others I dont pick her up and just soothe her back to sleep in her cot. We have checked things like temperature of the room etc but still cant get her to sleep longer. Otherisly this is now making us exhausted. Is this the 4 month regression that will pass in time or to do with milestones. Any body else have this
