I don't know what do.. Just need general opinions

I'm going to school for my Bachlor but I feel like giving up& just start working..my hub said just focus on going to school..but here's the catch I want baby #3 &my mom n law is fine with it because she stays with us(well I'm at school) and watch my kids...(I make my classes at the same time my kids are @school) so when baby 3 comes it won't be hard for her..my hub makes good money..so that's not a issue..but I feel like I need to do more.. And he says I do a lot going to school & being a house wife..but I just feel tiered and want to quite..what your opinion?
