My DS is 8 months old and has always been pretty bad at sleeping so we were advised by so many people including HV to use controlled crying on him to teach him to self sooth. We are 2 and a half weeks in and he still screams bloody murder when I put him down to sleep in fact se starts crying when I say "night night mummy loves you". It's killing me to leave him screaming on average 10-15 minutes before he drops off. Can anyone shed some light on this is he just rebelling because I'm doing something new or is he always going to cry himself to sleep?
