As long as she's in good health I say fair play to her.
For reasons I don't feel the need to go into on this forum, I was brought up from the age of 8 months by my grandparents. Their average age is now 78, I'm 26. They have always been able to provide me with everything I've needed as parents, and still do today. I never suffered any discrimination from my peers at school for having older parents. In fact, I'm grateful that I was raised by a loving couple with plenty of life experience - I'm sure I had a better start in life than one of the many children brought into this world by teenage single mums.
