Not sure if I'm posting this in the right forum, but here goes anyway.
My 4.5 month old gets 1 bottle each day to keep her accustomed to taking a bottle. We use Playtex Nurser nipples with the drop in bags; she takes this type of nipple better than any other that we've tried. We use slow flow nipples - should we switch to fast flow at any point? I've heard that bottle fed babies usually switch to fast flow around her age, but since she only gets 1 bottle per day I'm not really comfortable with switching her to the faster flow. I'm scared she'd choke.
