Before and after care

Kara • Married 🇨🇦 SAHM Girl 09/09/16 -x- Boy 08/29/19 Waiting to TTC #3

I'm planning on becoming a stay at home mom after my Mat leave and I'm thinking about starting a small before/after school care group out of my home. I live 2 streets away from a huge elementary school.

Problem is; I have no school age children so I don't go to the school. How can I find parents that need care for their children without being a total creeper
