Babysitter Needed for my Children - Full-time / Part-time

I’m out for work until the end of September and my wife has a knee injury jury which has made taking care of our three children in my absence very difficult and painful for her, we are looking for someone to help her while I’m gonna and if things go well after I get back as well. She would be home the whole time you would be assisting with the children as a nanny would. The only time she might leave the house or require you to come earlier than the hours stated would be if she has a medical appointment for her injury and that would be discussed and scheduled during a naptime so you wouldn’t be handling the kids all by yourself.
