Uncircumcised boys

I was recently bathing my grandson with my daughter and I asked whether she'd had any difficulties pulling back his foreskin. She was horrified and said she had been told to never pull it back under any account.

When my son was born, in the 1970s, I was taught that I must always pull his foreskin right back when changing and bathing him, to clean him and to stretch his foreskin.

It seems that mothers are now being given precisely the opposite advice!

I would love to know what other grans were taught to do, and did, with their sons.
