I get your point Mollie, i was thinking that when the american lawyer was explaining how she couldnt turn a tap on and so couldnt shower kids or change nappies as she had arthritis, and so was totally reliant on a nanny in the day and her dh at night. My iniatial reaction was horror then i thought that she could have been younger and had a disability restricting her in the same way and i wouldnt judge then.
I would never have children over age 40 i think its too old. However most of my opinion is based on my dhs experience, he was boprn to older parents, not IVF but a 'surprise' baby, his dad was 50ish when he was born and mum in her 40s. He hated it, they couldnt do the things he wanted to do, his dad unfortunately then suffered from ill health which majorly restricted them. He swears he would never inflict that on a child.
