Our family includes newborn twin boys (2 months), a 3-year-old boy, and 7-year-old girl.
We would be looking for help with the twins and the 3-year-old throughout August.
Starting in September our schedule may change as our 3-yr old and 7 yr old will attend school full time, but we may need help with school drop off/pick up depending on work schedules.
The most critical hours in Aug would be midday to early evening (around dinner). In September this will likely shift to morning and after school when all 4 kids are home.
