Hi, don't want to hijack your thread but as another childfree woman I am finding this interesting.
Funnily enough I always said I wanted children. Up to the age of about 18 I said I wanted at least 4 but preferably 6! I do really like babies and young children - not keen after about 8 years old. I always want to hold young babies for a cuddle.
I met DH and he said he wasn't sure he wanted children because of his upbringing. He was worried he would be as awful a parent as his were. We discussed it at long length and for a number of reasons we decided against having any.
He actually would have made a very good dad. We have looked after our nieces and nephews and had them stay with us for long weekends (even took a couple of them on holiday) and he has always been great with them. We have though always been quite happy giving them back!
We have never regretted our choice and we are both in our 60's now. A couple of times I have fleetingly thought "what if" but it really was fleetingly. When we look at the state of the world, all the crime, the overpopulation etc we often say to each other "so glad we didn't have children".
I have had some really nasty things said to me (DH never has!). I have been told I am not normal, not a real woman, asked why I bothered getting married if I didn't want children, told more times than I could count that I was selfish and that I would regret it and also told quite a few times that I will end up alone and lonely!
Even now I get asked quite often if I have grandchildren and when I say no get asked how many children I have. That starts the whole thing over again and I have had people say "Oh I'm sorry" to the fact I don't have children!
