Bonus! She can do whatever she wants with it
If i were the nanny I’d be more happy to receive bonus
I think you should gave her money that you can easily afford.
Bonus should be fair , she can buy whatever she wants ..
bonus that will be very helpful after the wadding
Bonus will be better, she can use it for her self
Cash will always be good vs material Things
as for me, i'll prefer just give a wedding gift.
Wedding gift is more appropriate.
Bonous will cheer her
