If you get a job and have kids later can you still feed?

i have really small, (and im talking wanna-be A's) and as much as i would love to hear you all tell me the downs of getting jobs, i just want to know one. see like i said, i have itty bitties and my husband is a big guy. though he would never ask me to get one because he is so sweet. but i hate having such small and i have been thinking about maybe getting a job, but i want more kids, so i was wondering, if i DO get one, will i still be able to feed. obviously if i cant then i wont get one but i was wondering if anyone knows
