My DS is 8 months old, and is teething badly at the moment. To add to his misery, he's taken to vomiting up his lunch (his best solid meal of the day) when he does a sort of cough/belch/projectile puke. He was diagnosed with silent reflux at 6 weeks,and has been on 2 sachets of gaviscon in his bottles. Is the gaviscon not working? Or is the humungous amount of spit he's swallowing at the moment make him cough/belch then vomit? He's never been a brilliant eater, but does 4 bottles a day (between 4 - 7oz a bottle)and 2 smallish solid meals a day. He had a bad cough a few weeks ago, and the blummin' cough seems to be hanging around still. Sorry about long post, but I do worry!
