Oh dear. Brooki for gods sake, don't make the stereotype worse!
Barbie -
I had my three children young (I was 19, 21 and 23).
I got pregnant easily, had pretty easy pregnancies, gave birth easily, breastfed easily, got my body back quickly, and have the energy to look after them all. Usually!
BUT. I'm 26 this year, and oh my god, the difference! Apparently the frontal cortex isn't fully developed until 25. This helps to control emotions etc. for me, it's absolutely true.
When I was 19/21/23, I had no fucking idea who I was, I tried to be someone else. I was jealous when others had babies, and wanted one. I chose a twat of a father for my first child, and I regret that. I dropped out of uni twice to have babies, and now can't go back as I have no funding left. I developed anxiety and god knows what else. I rented a horrible damp flat with my first baby and lived on benefits.
But now I feel like I've come through all that. I'm a confident, mature, strong young woman. I'm married to a lovely man and we have a beautiful house that we have the money to slowly decorate. Ironically, after three children I think I'm done childbearing but I think that only now, at almost 26, I'm just about ready to have children.
Your 20s are for finding out who you are. It's bloody hard to do that when you've got children!
