GG Leo has also done this, did the cc last night and it took over 2 hrs for him to go to sleep, however I did cheat beacuse I couldnt leave him completley so sat patting him etc. Hv told me it was because they are very clever now and no that if they cry mummy comes and associate sleep with feeding! Felt horrible last night though, but he did then sleep until 8.20 this morning. I dont think i will do it again more likely just to give him his food. I have stopped Bf now and he is on a bottle and had about 17oz today and 3 meals.
