I am beginning to research bottles, as I plan to breastfeed and pump from the beginning if all goes well. I know that wider nipples and bottles seem to be easier for babies to transition between, and recently saw Tommee Tippee bottles on a friend's registry.

Has anyone used these? Reviews are generally great, only one said leaks (still gave 5 stars) and another said the measurements were off (but that seemed to be the only review about that).

Any thoughts?
