This child having the milk allergy, fed on soya milk, from age of six months to one and years., the mother saw hair growth on back and shoulders, stopped soya milk after one year. Now on mothers feed four times a day and tolerating the same. No hair growth elsewhere in the body.

Mother's query is Is this hair growth is normal or abnormal? If abnormal then is it due to soya milk? Will it also affect her puberty time?.
