Need bottle recommendations! 🍼

I need to find a bottle for my 11 week old. I am trying to get her back to breastfeeding, I suspect that she may have reflux since she shows a lot of symptoms (not diagnosed yet) but #1 she chokes while eating and we try to feed her upright.

I am using:

Avent Natural 0 size nipples

I have also tried Playtex Nurser drop ins, while I think the bottle is helpful, I think it’d be much more useful with a slower flow nipple. The nipple it has is medium flow for 3+ months. It was a sample from my diaper genie.

I am looking into:

Tommee Tippee with an extra slow nipple

Munchkin Latch

Thanks in advance!
