DS is two months old and just started spitting up frequently, where as before he never did. I usually use the playtex ventair bottles and i love them, but since the 6 oz bottles are going to be too small soon (the ventair 9 oz bottles only come w/ a fast flow nipple), i bought dr. brown bottles b/c they are bigger. everytime i use the dr. browns bottles, he spits up....i'm thinking theres a correlation, but i'm not sure..
Re: Can certain bottles cause baby to spit up?
maybe the dr brown's nipple is letting him drink faster than usual?
you could always buy the ventaire slow flow nipples separately. that's how we use the 9 oz bottles.
