My daughter is almost 4 months and we’ve dealt with reflux since she was about 2 weeks old. She’s what they call a “happy spitter” meaning it doesn’t hurt her when she spits up/vomits bc it’s not acidic. We’ve tried everything and no matter what she cannot keep a bottle down. Sometime she spits up as soon as I burp her and sometimes it’s an hour later, there’s no rhyme or reason to it, but she has never kept down a whole bottle. Do you think a formula change would help? Also the daycare worker thinks she has a tongue tie which could be causing her to swallow extra air during feedings. Any suggestions or experiences you’ve had may be helpful. I’ll do anything at this point.
