I need a babysitter on Wednesday to do the following:

Collect my 2 1/2 year old son and my 7 year old daughter at the Collective at approx 11:30.
Mind them (park/playground/home/zoo – whatever is easiest) until I can collect them at approx 3:30.

Leads and recommendations greatly appreciated


Note: My son has a nut allergy and carries and Epi-Pen.  His allergy just requires that he be not fed nut products and a close eye kept on him in the playground in case he picks up something on the ground.
