Quoting hobbit*:" Before I had my baby, I basically had DD1 off bottles apart from one before bed. When DD2 came along ... [snip!] ... do it? Cold turkey or did you phase out one bottle at a time? She's still having one in the afternoon and at night before bed."
My SIL used the birth of our baby to get her 2yo off bottles. When I was pregnant and she was talking about the baby in my tummy she was saying things like, "You're a big boy now, bottles are for babies, do you want to give your bottle to the baby?" It took awhile, but it worked. He "gave" all his bottles to Lucas and drinks out of sippys or normal drink bottles now
