Oh gez... I really don't know anything about scabies and I'm not sure who's online right now. Try googling what your baby has and see what you can find out that way - at least until someone comes back online. I did find this place but I didn't have time to read anything on it so I can't vouch for anything it says - sorry. Normally I'd say talk to another vet but since there's a language problem...
