Childminder part time in Afternoons

Hi I am looking for a childminder for my 3 year old son who has recently been diagnosed with autism. Liam is a very happy playful child and really happy in his own skin. He loves outdoors playing with sand building with blocks and painting. He does have sensory issues with food and is really making great progress. Liam does need constant supervision and he could like any other 3 year old run off if not supervised. He works really well on one to one. He is starting an ASD preschool locally in September and I need childcare from 1:30 pm to 6 pm 2 to 3 days per week. Thanks for reading my post
