I said "I kind of sorta want kids". Ideally, yeah, I DO want kids. I see myself being a really good mother someday but it's not something I'm even THINKING about now (being 21 and single). I know some people who, at 18, had their whole lives planned on "I'm going to have kid #1 then, and then kid #2 two years later... etc etc" and I've just NEVER thought that way, I've never fantasized about a glamorous wedding or anything either. I've never had that desire to have a kid but just know that someday I will, if that makes sense.
I also live with my 4 year old sister and before that, was living with my now 8 year old brother. So I've been a second mother to all of my siblings already and personally, I like being able to pass them back off to the 'rents when they get on my nerves.
Honestly? I'm perfectly happy with Jackson at the moment. He fulfills my "motherly instinct" if you will and I am content with that. In 10 years, I'll be 31 and he'll HOPEFULLY still be around at 13 (Lord willing as my grandma used to say) and I can't say I necessarily want kids before that anyways so hopefully Jackson stays my baby.
But I guess I'm more of a "I'll deal with that when it comes around..." type person and don't really think or plan about it.
