Stephen, looking for a nanny in Beckenham

Hi,
We have two children aged two and three (1 boy and 1 girl).
They attend pre school from 8:30 -5pm.
We require some assistance on a part time basis.
Subject to change but 4-5 days a week, 2-3 hours per day, from 4:45pm.
time would be spent in our house, my wife will be present as she is WFH.
Duties would be childminding, light cleaning (related to the kids!), and kids meal prep and occasional collection from pre school (5 min walk).
it would be a fairly dynamic situation i.e we would expect occasions where my wife will be available and there would be less to do and other times where she may be out and we need cover until I can get back from work.
Thanks

Stephen
