We use the Dr. Brown's bottles for my son, and I was wondering if anyone has used the options kind (new one with the option of taking out the vent). How does it compare to the regular? I thought I heard that they leak more but I'm curious what people have experienced. I like the wide neck bottles, and I can only seem to find them in the "options" variety. We got some regular wide neck ones from my MIL that she had purchased a while back, but I can't seem to find them now.
