Health visitor said we need to stop feeding to sleep / playing white noise to sleep so DS learns to self settle. I stopped both two days ago and we've barely slept since. DS is screaming blue murder all day and night. Even I'm in tears. He only falls asleep if he gets so hysterical for so long that he passes out from sheer exhaustion. Or he falls asleep nicely on the boob or with white noise playing. Not sure why this hell is preferable. Please someone help
