Just that it can really scare them (and impact on their future sex life), or the opposite where children start imitating in play (sex) where they think thats what mum's and dad's do but don't realise its not something kids do.

However I think its perfectly fine to say that mummy feeds from her breasts. Paris was 4 yrs when I had Seth and we had explained to her about birth and breastfeeding. She knew that Seth was going to come out of my vagina and that Paris was born out of my tummy (c/s) and she knows all about breastfeeding.
