Babysitter Needed for my Children - Now Hiring

We currently have a (very energetic and adorable!) 21 m/o girl and are expecting a baby boy in late October 2026. We have a full-time nanny during the week, but we are looking for some help on weekends after the baby arrives. We will be around much of the time, so whether we need help with both children or just one child will vary. Hours/days (Sat, Sun, or a combo of both) can be flexible depending on availability/interest, and we can guarantee at least 15 hours per month, likely more. We live in Chevy Chase, Maryland, in a single-family home.
