Sitter Job in Casselberry, Florida

I am looking for a reliable person to care for my 2 year old son. Looking for one or two people that could help watch him when he is home sick from daycare, to be back-ups for occasionally picking him up from daycare if I need to work late, and for occasional nights or weekend hours. Prefer someone that could watch him at her home. I typically work three days a week 9-5, but am also on call, so someone that could help on short notice would be great. My son is developmentally normal, but has some medical needs related to his esophagus, so experience with medical special needs is preferred, but not required. Thank you!
