Hey I second Nan comfort we have used a few different ones to see if our daughter will take to them, currently she has a bottle at night { NAN OPTI pro } so she gets used to it for when I get injections in my spine {I can’t feed her for 2 days after}
My 10 month old seems to really like the Bellamy's organic formula. I tried him on bubs organic and one for colic before that, but he really seemed to like the bellamys and we've never had any issues.
We’ve tried A2, Mumamoo and Nan Comfort. He didn’t have any major issues with the first two but we’ve enjoyed Nan Comfort the most. It’s affordable ($21) and he seems more content with this one than the others 😊
