Nanny Needed For My Children

This is a very odd need - about 2-3x a week, I need someone to pick my girls up from school and hang out with them for an hour tops. My husband or I can come grab them by 4 p.m. usually. There is a playground at the school you can stay and play at until we arrive, or my parents live about a 10 minute walk away. If you could walk them there, then my mom can do the rest. Just feel like it might be easier than dealing with booster seats? And finally - most likely a different combo of days each week (I know - its a crazy ask!). Budgeting for about $60/week. Thank you for anyone who could fill this role for us!
