Ok so I just turned 18 last year when I had my son and was living with my mom and her fiance before and all through out my pregnancy. I was 17 then so my mom's fiance is claiming me for taxes. They decided that from the money they get they were gonna give me $650. At first I thought I'd get a new computer since mines is a little out dated, and I'm in school, and save the rest and add to it over time but now that I think of it more and more I feel like that'd be really selfish of me to do considering I have my son now so I should do more for him than for me. So I'm kind of stuck. Do I go on with the new computer or do I save it all while still adding to it and only use some whenever it comes to my son? I know I sound pretty dumb but I just need some advice on which decision is better.
