Joy, family for nanny sharing - M6S West toronto (bloor west village / swansea) for the 12 September 2022

I am looking to join a nanny share in my area starting in September 2022 when my son will be 15 months old. I start work in the afternoons, so we will need care only during the following hours: M-Th 3-6pm and Fridays 11 or noon-6pm. Hoping to find an arrangement that costs less than the $175/week rate for half-day home care. If you have a two kids and a nanny already, bringing my son on board as a third has one great advantage: I can fill in until 3pm when the nanny has a sickness/emergency. My husband and I are fully vaccinated.
