than id say its time my son is 6 weeks and took for ever trying to drink his bottle a lot longer than i thought he should so i moved him up to a medium flow nipple

if you move to the second nipple it will be too fast, just be patient

I use the same bottles and I was told, by my pediatrician, to change the flow of bottles as you do foods. Your baby more than likely hasn't started solids yet, so you're probably fine. My baby, at that age, took a long time to drink too....probaby 20 - 30 min. Once you start solids, at six months, change to fast flow.

as long as your baby keeps gaining weight regularly she is getting enough milk :) if the flow is too fast she wont have to suck hard enough to get the formula and will overeat, start a stage two nipple at 6 months when you begin solids, or in the event your baby falls below her normal weight percentile

I use the same thing. My daughter is 8 months old now and I switched her around 2-3 months. she did fine with them. I'd try it and see, you'll know if its too fast for your baby.
