NAKED!!! ok??

so I would just like people's opinions on this. when my babies where young I used 2 bath with them even at toddler age if I was having a bath and they wanted 2 get in then sure. No problem! Iv just been told that it's wrong and a mother should never bath with her baby and by doing it makes me a perv! I don't agree with this at all. what age do u think it is ok for your child to see you naked and at what age should you stop.
