I didn't feed to sleep, but my daughter had a bottle until she was 5 (stopped at christmas just before she started school)! Nothing wrong with it! She is fine, teeth are fine etc! We had trouble with her sleeping until she was 8 months when we went to a sleep school. Easier ot do the sleeping thing with people around. It was such a relief!!
good luck and really I don't think any of us reallly know what we're doing, we're just lucky we have bb to bounce ideas off!!
