I love kids, I never really wanted them until I got a baby nephew when I was 22. Unfortunately I can't see him or his new younger brother anymore (my own brother, their dad, is a cunt) but they really triggered my maternal instincts. I'm 26 now and would quite like to think about kids 30-32 if life works out that way. I definitely don't want them any time before that, I only just literally this month qualified and got my first graduate job, and I want a good solid five years of hard work, learning the job, seeing where I can progress to etc. as being female, once you get pregnant your career is pretty much kaput for a couple of years at least. Also, in my line of work, if I got pregnant I'd be immediately removed from a major part of the job (risk issues as there are a lot of assaults) which would suck.
I look at people my age with kids trying to do what I'm doing, and struggling with childcare, with paying for a babysitter, with trying to get a job with short work shifts or stay near their kid's school, and thank fuck I haven't had them yet. When I finished my MA this year I applied for every single job I liked the look of in the entire country, and then moved to the first place that offered me a job. There were literally zero jobs in my field in my city (a few have popped up now but I didn't wanna hang around just in case). I always had family or relationships keeping me around in my home city, but now I don't and the freedom is intoxicating. Suddenly I'm living in a brand new city doing the job of my dreams earning more money than I've had before (not huge amounts by anyone's standards, but still more than I've had before and for less hours), I can't imagine how I'd have been able to pull of a two year MA working 70 hours per week if I'd had a child to think about.
If I don't have them biologically I'd love to adopt. Or, both. I just know that someday I want to be a parent, just not yet. I adored being a hands-on auntie to my nephews and it kills me every day I don't get to do that anymore, from the grossest parts to the most 'boring', I loved it all, nothing made me happier than taking my little toddler nephew out together for the day, I swear it was as close to heaven as I've ever felt. The only thing that concerns me is I don't know if I'll have them before I've lost parents as my mum already died and my dad is in his sixties and has emphysema. I would be devastated if I had kids without their grandparents around but you don't know what life is gonna deal you.
