So my poor little boy has a possible case of tonsilitus! He's been prescribed penicilan but the doctor wasn't 100% sure if it was tonsilitus though, his only symptoms were a high temperature and a sore, red throat. Although as I was putting him to bed tonight he was very very sleepy that's unlike him and he projectile vomited all over me. Barely drinking any bottle and won't eat as much. Has anyone else's baby had tonsilitus and did if start out this way? Should I give him the penicillin? He's never had it before so I'm very worried about him :( x
