Do u think Dr.browns bottle help solve my problem?

Fiona

Hi I am first time mom of 6 week old beautiful daughter.

Our daughter has gas issue(I think) and she always look so uncomfortable after being fed from bottle. She gets breastfed during day and she seems slow eater so I got preemie nipples for her avant glass bottles otherwise she makes big mess while drinking

So considering all that, do you think Dr. Browns bottles(preferably glass bottles) will help her gas issue? Also What do you think of flow in dr.browns?
