Ok the right age again

It depends! If your children are brought up in a stable two parent background where you and your partner have a good loving and positive relationship, then your children are likely to follow your lead and wait until theya re also in a good stable and loving relationship before starting a family. If you and your partner are separated and particularly if one aprent refuses to allow the other parent to see the children, then statistically speaking, children brought up by single aprents are significantly more likely to have children whilst still children themselves. This is probably due to the lack of love and affection they get at home from their single parent and possibly due to the benefit system (in UK) where single parents jump the housuing queue to get their own property regardless of their age. I hope you are in the former category - bring your children up properly and they are more likely to be sensible and wait until they are ready - probably mid 20s - before having children.
