hai
hope by this time ur son problem wud be solved,i had same problem with my kid when v were in b'lore one yr back it cud be bec of climate variation but with no option we went to skin specialist there.after coming to US also i had same issue but with my friend advice i bought Aveeno baby moistorisier and tried still now i don't have any problem with her skin.
primarily thing is we shud apply moisturisier after the bath daily so as to keep it soft and silky.this cream really helps a lot but iam not sure whether we will get in india but i guess we can good substitute for that hope this post helps.
with regrds,
