Live in Nanny of a 1.5 year old, and before/after school care of 4 year old

We are an easy going family looking for a live-in Nanny (Chiswick, London) to start mid September.
It is important you already have pre-settled status and are covid vaccinated.
You would be staying in a double room, with an en-suite bathroom, on the top floor of the house.
During normal working hours, you would be looking after our son (dob 01/2020), who is an active and fun little boy. Our daughter (dob 08/2017) goes to school (15 minutes walk away), so you would need to get her ready for school, drop her off and then pick her up and play with both until around 17:30/18:00. Friday is usually half day.
