Building Our Babysitter List!

We are looking to expand our "refrigerator list" of folks we can call on short notice with child care needs, particularly when school is closed or our son is home sick from daycare. We are newer to the area and don't have a support network. Both our families live too far away to help out. I (mom) work from home, so unless I'm traveling for work, I'd always be close by to support as needed. Fully attending to my son during a workday isn't reasonable, and I can't keep falling behind at work. Just needing to build our network! Thanks!
