Hello, this sounds exactly like my DS at the same age and after being initially told it was reflux we got him tested for allergies as it seemed to getting worse and he is dairy intolerant. We cut it out and made such a difference, not sure if you are still BFing but we switched to Alpro and he gulped it down and loves all the dairy free alternatives. It might be something different but might be worth getting her tested. Good luck.
DD had silent reflux as a newborn which improved with Gaviscon and once she started solids. However she has recently started being sick once or twice a day. Not massive amounts, just a tablespoon an hour or so after milk feeds but it's very curdled.
Has anyone else experienced this? She's still not really eating solids properly, mostly chewing and spitting them out again.
