Any advice gratefully accepted. DS is 12 months (next week) and will not for love nor money for the last 3-4 weeks sleep in his own cot. He will fall asleep next to me no problem, but will wake around 4am and scream. I am physically and mentally exhausted. He screams constantly as of late. I physically cannot leave the room or move an inch because he screams. I love him with my whole heart but he is sucking the life out of me with the constant crying. Can someone please offer any advice because I feel like I really 💩 mum 😭
