We used Gaviscon Infant when DS was little (no one ever questioned it?). It did help in some ways, in that the volume that came up was less, but what did come up was so thick he would sometimes choke on it, especially the times it came out his nose . But as he was borderline FTT everyone was happy that he was keeping more milk down. I personally found that the AR formulas were useless and upset his tummy.

I think you are right to seek a second opinion. If your baby is happy and healthy, and still gaining weight, then I'm not too sure what the problem is (apart from the mess and washing for mum ). Hopefully another paed will be able to give you some more suggestions.

Good luck . And remember, it will get better, they don't chuck forever!
