Yvonne was very helpful in finding the perfect sitter for us. Our son has epilepsy, and she was very reassuring that she could find the right person, with medical training even, to ensure our son got his medications and to ensure we felt comfortable leaving him with a stranger. We typically only leave our two boys with relatives, so this was a leap for us. But our sitter, Sharon, warmed up to our children and our friend's children instantly and all 4 kids really liked her.
