I think it depends on the nationality and age of your nanny, TBH. Most British nannies above 23 would anticipate, if not downright expect, a cash bonus, IMO. In London I've always had the after-holidays meet up where everyone is asking each other about their bonuses
- saying this as a nanny!
A young, single girl from Europe will more than likely be chuffed with vouchers from Westfield (brilliant idea) as can spend them on whatever, or a bottle of something and some chocolates plus 20 gift voucher to a shop you know she likes, etc.
More important to me is the card that they write - you get one time a year perfectly handed to you to say something lovely about how she's been with the children, once I got 50 quid with no card and was so
, as for me it was more important I be recognised for my hard work.
I've never gotten a week's wage but I do generally get 50-100 plus some little thing from the children.
On the other end of the scale, I have a partner who is also a nanny, she get's - wait for it - a month's
wages in CASH plus 100 John Lewis / Waitrose vouchers, plus some smellies/chocs from the children. It's rather incredible to me, to be honest, so a week's wage is certainly not top in London as someone else suggested! These are bankers living in Kensington, though, and she has been with them nearly 3 years. This year as expecting DS1 will more than likely get a baby gift also as going on mat leave before Xmas.
