Working mom with energetic toddler son who likes someone to watch over him while he spends time on his devices and toys.

I need an occasional sitter to help out with child care when I have work emergencies or other engagements. The sitter just has to watch over my son, keep him safe, provide snacks as required and keep him entertained.
I need someone who is calm and gentle with children.

The schedule includes some Fridays 10-3pm. And other weekdays on demand around the same time.
