hmmmm I have a few different thoughts on this.
I see no reason why age should be an issue to being a parent.
I was raised by my paternal grandmother for the most part. - she is 84 now and I am 28.
I also believe a woman should be entitled to have a child of she is willing to care for it.
having a child is something women take for granted - until they can't.
she might be a most fantastic mother.
on the other hand parts of me scream "no, it's wrong" - but I can't come up with an valid and justifiable reasons why.
