So we started Andrew on 3 months nipples at about a month old...and now that he's 3 months old, lately, sometimes he's collapsing the nipple.
It's just because he's sucking too hard, right? It's not possible that he is intentionally "biting" down if he doesn't want anymore food? I don't know if I want to switch him up to a stage 3 nipple...it seems really early and I feel like if he eats too fast it could make him vomit more? Then again, he's really burpy lately so maybe he's sucking too hard and swallowing too much air. I'm confused. Obviously. haha
