DD came out in blisters 2 weeks ago today, the ones on her hands/feet/face had all gone by last Sunday but she still isn’t eating properly and I can see some sores in her mouth - she’s putting food in her mouth and trying to chew but spitting it out. Is it normal to go on for that long? I’m popping some anbesol in her mouth to try and help but not sure what else I can do.
