I am in a very similar situation. I am caring for a toddler who is immune suppressed so she can't go to a sitter or daycare, so she qualifies for a nurse. I basically spend my days sitting on the floor, being a preschool teacher. I am also a PT, an OT, and a SLP. Sometimes I feel like I want a medically complex patient, but on the other hand, there are worse things than working in a clean house with nice people. I view it as rest and recreation to make up for all the years I was working like a dog. So, if you really hate it, move on. But, seeing a child grow and develop can be rewarding also.
