I'm into day 3 of doing controlled crying with my 9 month old, and last night he fell asleep without even crying but woke for a little cry during the night, but tonight i have put him down and he has been screaming for nearly 20mins, it is so upsetting and I am on my own, my partner is at work. Why is he crying tonight when he didn't last night? Thought we were making progress? I know it can take a lot longer but i thought we were getting somewhere, i can't stand listening to him cry..
