We are a family of 5. We have an infant daughter, a 3-year-old son, and a 4-year-old daughter.

I (dad) work from home and will be in the house except to take my daughter to her therapy appointment.

Mom is a stay-at-home mother but would be sleeping after taking care of our infant daughter overnight.
For the first hour, there will be two children (a 3-year-old and a 4-year-old). At 9 am, we take our daughter to therapy. After that, it would just be our son.

There is no other requirement than watching the children.
