Work or Stay At Home

For months now during my maternity leave I’ve been struggling with the decision to stay at home with the baby or go back to work at least part Time. If I do go back I will start next Monday and work 2-3 8 hour days. Me and my fiancé currently live with his parents and don’t necessarily need the money, however today is his first day back at work and I’m already feeling emotional about being home with the baby all day every day. I love my baby but I’ve been working non stop since before I had him. Just wondering what other moms would do in this particular situation? Plus I will be going back to school full time in August. Advice?
