your child has developed acidic stools, could be because of some antibiotic or excessive loose motion ( developing sec lactose intolerance
). Zinc oxide cream may help but if still this does not help, you can use some topical steroid
cream for one or two day. Hope it will alleviate the symptom of painful rash
.And also use orally some probiotic which will help in reducing the frequency of stools.Throat inflammation
is a different entity. should be treated differently by antiinflammatory ,antihistamines and decongestant.
Hope you are guided better
