Drop-in daycare/last minute babysitting

Good morning, neighbors! We've been having a tough couple of months with our nanny and our extra family help getting sick or having to cancel at the last minute. We'd like to line up a backup plan. We'd love someone in the neighborhood that just does occasional babysitting who we could call way too early in the morning to start at 8am in our home. If that's not feasible, are there some drop-in caregivers in the neighborhood? I seem to remember some posts a while ago, but I didn't save anything. Thanks for your help! Rachel Sent from my iPhone
