I've been doing it for 3 nights now. Tonight is beyond a joke. I'm 20mins in and watching her on a monitor during checks. She keeps collapsing and hitting her head in the crib. Any advice? I've ran in to grab her. She went with a thud each time and I've picked her up and comforted her. Surely there's a better way of sleep training in a 1 year old? This is breaking my heart I feel like I'm torturing her
