I am not trying to be a dick here, but I am tired of seeing young mothers. You're 18... LIVE YOUR LIFE! Go to college, get a degree, get a career, travel a bit, see the world... and THEN talk about having kids. You and your boyfriend at 18 & 19... not to sound like a dick (sorry if I am coming off as one), but young love doesn't last forever. Who knows... you and your boyfriend could be together for a long time... or you two can get into a huge fight and the relationship will be over, leaving you as a young, single mom. I've seen this scenario happen many times.
Wait it out, see where you are your boyfriend are in about 7 years... and if you are still together, talk about having kids again. If he cannot respect your wishes to wait a big longer, he is not the one for you.

Your boyfriend is not being realistic. Next time he brings it up, assure him that you want children one day, and then tell him why you both need to wait. Regardless of money, most 18 and 19 year olds are not mature or stable enough to raise a child.
