Thank you for posting your query with Health Care Magic
I can understand your concern. If you make your child wear diapers, then probably the baby has developed nappy rashes. There are various ointments
available in the market like EziNapi available in the market. They should help resolve the rashes. If they are even more severe, then you can use a siloderm cram. But i would recommend you avoid diapers and use cotton soft cloths instead. That helps the most. For a proper prescription of these creams, consult your pediatrician
. Now as for the frequency, i need a little feedback
1. Is your child breast fed exclusively? If yes, then she might have got a few antibiotics via mothers milk and that may killed the helpful bacteria in her stool too. If that is the case and the mother has stopped taking antibiotics, then it should resolve soon. Else some preparations containing helpful bacterial spores can be given. They should reduce the frequency.
2. If your baby is top fed, then i suggest you take good care of her feed hygiene.
If the problem of crying during passing urine continues, i suggest you get an ultrasound
of the kidneys and bladder done along examination of urine.
But i believe your baby's problems should resolve with the above measures and she should not need all these tests
Hope that helped
God bless you
