My DS is 15 months and has ulcers on his tongue. He has had a really bad week. First terrible teething with molars which put him off his food. He then came down with a virus with a temp and also ulcers on tongue. Have seen doc who said not to worry about food but it feels like ages since he has eaten anything. Any advice on food I can temp him with? Or how to help him with pain of ulcers? Calpol / Ibroprofen don't seem to help. Thank you
