My wife and I have our three kids, Sebastian (2.5) Azalea (1.5)and Darianny (10). We just need some help watching the kids while my wife goes to her classes. I come home from work at 1PM and can take over childcare then. We also have our Golden retriever JJ and our chickens in the backyard.
We need help while we are both out of the house to keep an eye on the kids. They play well together both inside and outside and are easily distracted by a TV when those options are not available. Fairly capable and self-sufficient, although the youngest likes to dump things out if you are not careful and leave a glass of water unattended.
Time frame may change as classes change, but should be consistent through each semester.
