new, with second baby, and weight left from both babies!

Hi! i'm new to this site. I'm joining to kind of guide myself into weight loss, loosely. I'm not being too strict with my caloric intake, as i'm breastfeeding, but i do log things simply to have an idea of how much i'm eating, and how much i should be eating. I am having a hard time fitting in exercise.... I work 32h/week, have two kids, and am also in nursing school right now.... Any suggestions on how to fit in some exercise in an insane schedule?
