Fathwa, - It is permitted for a father to see his baby girl’s private parts (e.g. while changing diapers)

Question:
I was told that it was haram or highly discouraged for a father to see
his infant daughter's awarah (private parts) for example, if he is
changing the baby. And is there an age limit? Can I get both the
Hanfai and Shafi'i point of view.
Answer:
Walaikum assalam wa rahmatullah,
Small children have no awra, and it is permitted for even those not
related to them to see their private parts�such as when changing
diapers, etc. [Ibn Abidin,Radd al-Muhtar; al-Fatawa al-Hindiyya]
It would only be impermissible when there is fear of fitna or desire,
which is not normally the case.
This is also the ruling in the Shafi`i school, as explained by Shaykh
Amjad Rasheed. (See Shafii fiqh archives at on this site.)
As for the age limit, there is no specific limit, except that it is
proper that children�s awra be progressively emphasized such that by
the time they are small, they should normally be covered in dignified
ways, and by the time they are 7 or so, they should be properly
covered and when 10, it would be obligatory to discipline both boys
and girls regarding proper covering.
And Allah alone gives success.
