One of my relatives had two sets of children - three when he and his wife were young, and after a fifteen year gap they had another two. If I remember it correctly, this is what he said, some years ago, shortly before the youngest had his 21st birthday...
It is much better to have your children when you are young. It's harder for you and harder for them if you have them later in life...
- When we were young, we had hand-me-downs, and it didn't matter if the children wrecked stuff. We had lots of precious stuff when we had the younger two, and we didn't want them to break the porcelain collection, or ruin the nice furniture we had.
- When we were young, our bodies were more capable for young children. We could stay up all night, and party the next day; we could run and play more - you are the ideal age to have children.
- With the first three, we were the same age as the other parents at our children's schools - we could make friends more easily - younger people tend to look at you, when you are the age of their parents, and treat you differently, and hold you at arms length.
