I've never used chamois butter, but have used something similar called "3B Action Cream"... no running around and crying - except it was expensive.

Then remembered all the nappies I have changed and went and got a big pot of Zinc and Castor Oil cream from the chemist.

To prevent chaffing and "nappy rash" and very soothing and healing during and after a ride also. Its made for sensitive baby skin, so should be ok on yours too. AND it is loads cheaper!!!

Good luck
