I wish my child would sleep in his bed😕 the moment I put him in there he wakes up crying... He was never like this until last week. The only way I've gotten any sleep is if he sleeps with me which I really really hate doing! I have to constantly be holding him or him be on the boob. It's tiring getting not just 5 mins to myself 😔 my ex said to swaddle him and put him in his bed but he doesn't like being swaddled he gets frustraTed and eventually kicks himself out of it. I've tried everything and I was so tired the other night I fell asleep with him and actually got sleep the past 2 nights with him, but he needs to learn that is where he needs to sleep he can't sleep with me!
