My 12 week old has been formula fed (SMA Gold) since he was 3 weeks old. In the last 4 weeks he's been throwing up an awful lot after feeds and his weight gain tailed off at the same time. I'm not unduly concerned (he's on the 75th centile!) but I'm just wondering whether switching to another formula might help but nervous that this might introduce another issue, i.e. upset his tum. Any advice from anyone who's switched would be gratefully recieved!
