There are pros and cons to everything. My mum had me at 21, which these days is considered very young, but was less so in the 70s. For me, this was a positive experience. My mum had loads of energy - more than friends' parents who were older. She had fun, creative ideas for things to do when friends came over. Whereas when went to friends houses, the parents wouldn't know how to interact and would serve boiled cabbage for dinner 😂.
The second advantage is that I went away to university when she was 40 and my sister a few years after. So in her early 40s, she suddenly became free again. By that time, she and my dad had more money so were able to travel to far flung places and still had the energy to do so. Also, her career had taken off and was at its most demanding, so she wasn't having to balance that with childcare.
So there are lots of upsides to the route you have chosen.
I don't have children by choice. I'm happily married and we are able to please ourselves. I worry that we will regret that when we are older and need more support. We will be relying on our nieces and nephews wanting their inheritance enough to come and visit and help us out 😏. But when I hear about the struggles of raising kids in an age of social media and political uncertainty, I'm definitely glad I don't have to deal with that. Not having kids has allowed us to pursue our personal interests unencumbered - so we've set plenty of educational, sporting, musical goals and have great achievements in those areas. Overall, I'm very happy with the decision we've taken, but it's lovely to have children in our lives also and we will soon be relocating to be closer to family.
