I 100% did not want kids. I loved my life with no responsibility other than the dog.
We got to a certain age and didn't know exactly what we wanted to do around it so "left it up to fate". DD came along.
I freaked out when I saw that line on the test. Didn't know how on earth I would do it. No clue how to even talk to kids half the time.
Got my head round it and calmed down slightly. Baby arrived and genuinely, I can't explain it, but I just knew I'd do anything for that little pink bundle.
It is exhausting. And stressful. And you question yourself constantly. But then they giggle at you, or smile, or say "awww mummy" when they put their head on your chest for a cuddle. And it just feels worth it. For them.
Wouldn't want to go through it for anyone else's kids. I'm still not a "kid person". I don't get broody over babies (puppies though....I'd have them all!!). I know I'm done with my one DD. But I'd walk through fire for her.
If you think you want a child, then go for it. You'll love them more than life itself and although you'll never sleep again, you won't really care. If you don't want them and you're just trying to talk yourself into it, don't do it.
