I have four children and my 5wk old DS is unsettled day and night. He'll sleep maybe 3 hours between around 11pm and 2am, then he'll be unsettled sometimes the rest of the night. So long as I hold him tight in my arm, he'll be more settled. We've swaddled him, and whilst that helps as soon as we put him down to sleep on his own, he grizzles and gets increasingly upset until he's picked up again. I'm breastfeeding fine and he's putting on weight so i know there's no problem with my milk.
He won't really have a decent stretch of sleep in the day either. I'm shattered and don't know what to do! Please help!
