Bottle issues

Katie

So my LO was doing just fine with the bottle for her first three weeks. She's almost five weeks now. My husband gives her a bottle in the evening and another in the morning. The rest of the time she is nursed. About a week ago she started getting really fussy with the bottle. She latches fine but then in the middle of feeding she starts crying or screaming. We are thinking it's gas but we are just so frustrated. We have used Dr. Brown's bottles and the flow is just too fast. Same with MAM. We are using the Kiinde system and it has been working just fine up until she started getting fussy. We like the flow of the nipple because it doesn't pour out of her mouth and the bags are so convenient.

WE NEED HELP! What do you moms suggest? I've been thinking about the Minbie bottle system. Anyone have experience with that?
