I often hear people say, 'I had my DCs in my 30s so I'd had a life first' (as if by the age of 29 you've experienced all life has to offer), or 'I had my DCs early so I can have a life once they've flown the nest.'
I'm probably reading too much into it but it seems like such a negative view of what life with children is like, as if being a parent is such an awful slog that they are dying to be free of it. And it's like they feel they can't do anything for themselves while they are raising children, which is surely just going to lead to resentment.
