I started gradually talking to my daughter about sex when she was oh, probably 6 or 7 years old.
I breed dogs so I haven't really had to talk to my children ...As I said before it really depends on the child. I personally think some mothers dress their little girls in clothes that just shouldn't be on a little girl. Or the moms who get their little girl's hair dyed to match theirs really amaze me. I think our children deserve a childhood not to be made into little mini me's or wear sexy clothes at a young age. But thats just my opinion.
