We ended up giving DS a dummy in the hospital! We had a 4 night stay and i think on maybe night 2 or 3 we gave him one as he seemed to want to suckle and it comforted him. We also co-slept from day 1 and he was feeding every hour or so I think, took him 10 mins each feed and was looking for something suckle after each feed. He never suckled on my boobies for comfort as such and I could never comfort feed him even if I wanted to but the dummy he loved. He was never confused either and we used a big cherry one from day 4. Now he has the dummy at night only and again he looks for it after he pops off the boob. I also feed him to sleep. These things are apparently 'not ok' but "meh" whatever! I don't know why woman are told to teach their babies to not want boob or not want to suckle on a dummy for comfort. He does wake for a few night time feeds and when he spits the dummy out I know he wants boob. He feeds in about 5 mins and once that dummy is in he goes straight back to sleep. I think that if you want to try it go ahead
