I purchsed one of these for my daughter when I was trying to find the best bottle for her. This was not it. It had a strange square-ish nipple that she just did not like. She was holding her bottle yet then, but it would have made it more difficult for her if she tried. She would refuse to eat if I used this bottle if no others were clean. I do not suggest wasting your $$$ on these at all.

Oh and they did not fir it my diaper bad well wither, the pocket was too small.
