my ds has decided at 1 year that now he cant sleep in his crib! he has been in it since 7 weeks and now i cant put him in it asleep, no less awake. as soon as he hits that mattress, he is wide awake and screaming! i have no idea what changed. i tried CIO and he cried off and on for 2 hours! i had to get him. any advice on what to try next? after the 2 hours, he slept with us, which i know is wrong, but now i think i made him scared of his crib!
