DS will only sleep on me at night. Help! It's 3.15am and every time I try and put him in his cot he squirms and cries. He is fed, burped and nappy changed. It's been going on about 2 weeks now and I'm losing my mind. He is 20 weeks old. DH can't help due to his work patterns. My family live too far away to help at night. How do I get my baby to sleep in his cot?!
