Not sure if they do them in the states but I can’t recommend MAM bottles enough. X
we just switched to the philips avent and he loves them when he was born all he liked was dr browns but when i switched he had no problem he loves them
The boon ones can turn into sippy cups, and the Dr Brown's narrow ones can too
You don't need to use all the pieces in the Dr. Brown bottles. Just the bottle, nipple, and ring to hold the nipple in place. Maybe try that before buying something new
Your baby is 9 months and won't be on a bottle more than a few more months so idk if it's worth investing in more bottles at this point.
MAMs and como tomo are great and easy to clean.
I switched from Dr. browns to Philips avent natural flow glass bottles, i love them!
