It should be pretty easy to outsmart a child....... they aren't intelligent, albeit bright in some circumstances.
Story time with teddy bears, bake a cake, make a card/drawing for mum/dad etc.
I have experience with childcare. I've babysat my 4yo and 2yo cousins at the same time, and I often volunteer at our church's nursery. This is my first babysitting job where the parents don't already know me. I am crazy nervous and want some advise on how to impress them and maybe make this a permanent thing. Thanks in advance.
