Playtex Premium Nurser baby bottle Review

I do not like these bottles for my son. They were very convenient, but the added cost of liners, the poor nipple flow and the fact that they did not work in our bottle warmer just was too much. I could never tell how much formula my son had already consumed, and it was impossible to mix one bottle at a time in the bottle. I just gave up on them because they were too much time and energy wasted. We ended up sending them to daycare. Yes it's more time consuming to wash bottles all the time, but I think it's worth it.
