My youngest was 8mo old when I opened my dayhome and she joined us for all of our activities (if we were doing art at the table she was in a highchair playing or watching us). At naptime, I breastfed her in the playroom and she sometimes fell asleep and sometimes didn't, then I would carry her upstairs to her crib. I would have your hubby and baby stay with you and the dc kids for most of the work day for the next month....gives baby and you time to adjust to having him there while you still have an extra set of hands to help out. Good luck
