Tips for a week solo?

My husband is going to be out of town for a funeral and a work conference back to back (when it rains it pours) this upcoming weekend and following week. I mostly WFH with LO in daycare 8:30-3:30 but will have to do drop off/pick ups by myself plus the entire weekend alone. I realize single mothers do this all the time, but since I’m used to having a partner, do you have any tips for how we can prepare before he leaves or routines that will make it easier with just one set of hands?

Edited to add: LO is 4 months old
