Botabee Soft Spout Transition Sippy Cup Kit for Comotomo Baby Bottles | Conversion Kit Fits 5 Ounce and 8 Ounce Bottles | Sippy Cup Baby Bottle with Weighted Straw and Bottle Handles (2 Pack, Green)

It was exactly what my Niece wanted for her 6 months old, and she was thrilled... Many thanks for the speedy delivery... :)))

These are so great! My 7 month old can easily grasp the bottle by the handle and drink it while leaning back. It helps with preventing chocking as well since it works like a straw and you have to suck to get the drink out.

Buena opción para hacer la transición y la bebé encantada

These are awesome attachments to transition from an infant to toddler cup however it does leak but not terrible however the attachments fit nicely

We went through a dozen different types of training and sippy cups! Coming across these has gotten my baby to understand how to suck and he actually gets water unlike trying to learn in sippy cups that their little bodies have to work so hard to get anything out of when they are just learning. We love these bottles and he is comfortable holding it already. Plus, saves on storage big time because you already have the bottles!!! Love this!
