My dd is 17 months and came out with this horrible rash this morning all over her body (images attached) they have gotten worse throughout the day and she’s not very happy with it! We’ve been to the drs this afternoon who have said they think it’s a delayed reaction to the penicillin she was on recently and just prescribed antihistamine. I just have a weird feeling it’s something else as she’s been on penicillin a few times and this has never happened. The antihistamines have done nothing so far (6hrs later). I’m just a worried mum. Has anyone has similar before? If it’s any worse in the morning I’ll be taking her back! This is also all over her face and everywhere on her body!
