As a mother to 4 children, ranging in age from 14 down to 4, all I can say is, do what you feel is best, BUT, know that you are going to be missing time from your children at the age they need you most. Currently I am still doing my prereqs. My 4 year old in particular gets very upset when he knows it is a school night. This weekend I am studying for my final. He keeps telling me that it is his turn to play with me and that he "misses me". Rips my heart out. I know what I am doing is best for my family and I know I can't put it off any longer (I'm 39), but it doesn't make me feel any less guilty.
Don't let anybody tell you what to do, but make sure you think of all angles. Best of luck in your decision.
