DS is 10 weeks old and since birth wouldn’t sleep anywhere but in someone’s arms. I was able to lie down and rest (not sleep) with him on my chest or next to me in my arms. As the weeks have progressed, now he will only sleep if I’m sat up holding him in my arms. We’ve had to resort to co-sleeping as he will not touch his cot but he won’t even let me lay him down in the bed with me!! Hellllpppp!!! I’m going insane
