I am currently using the Playtex Ventaire bottles with stage 1 & 2 slow flow nipples. Today, my babysitter said my LO was choking while eating because the flow of milk is too slow for him.
I thought it was best to keep them using slow flow instead of fast flow. I BF when we're together, morning, evening, and weekends. He only gets 3 bottles a day while I'm at work.
the weird thing is my MIL watches him too, but she's never said anything about the bottles.
What should I do? How often are you supposed to change bottles/nipples?
