Good luck ~ I know that many providers return to work with their OWN week 6 week old and are able to make it work so this would be no different.
My one peer when she went back to work her infant just went around with the rest of the group doing school drop offs and babe napped in the stroller or infant carseat as needed for morning and she breastfed her out and about and so forth and than was home to sleep in her own bed for afternoon naps as needed.
