I’ve only tried changing teat sizes not the actual bottle. Will try that thank you!
Could be the shape or flow of the teat. There are some bottles marketed as best for bf babies such as lanisoh due to the teat shape being similar to a nipple. Could also be the temp of the milk. Our LG is formula fed but hates if we give her premade straight from the carton or left over that has been refridged then warmed unless its the same temp as her usual milk
The only bottle my first baby would take was lansinoh, even then he eventually refused that too. I’ve found with my second though he’ll sip milk out of a straw/sippy cup or open cup rather than drinking it like a bottle fed baby would but he’s still obviously getting the milk x
Oh could be the ripple size

There are # on it, my girls using 6M +
At that age I’d try a cup x
Have you tried changing the bottles? My lil girl would refuse Tommy tippee bottles - she only liked MAM xx
