How can yummy chocs ever be mean? Avoid only if the recipient is extremely weight conscious, whether dieting or not.
I tend to buy a selection of small gifts - chocs, candles, picture frames, all costing between £3.00 £7.00. I wrap them, but do not label them, so I can easily find a gift if I am given one unexpectedly. Also, if any babysitter gives my sons what looks like a very big gift (one babysitter bought gifts for dh and I as well as our two children)I can give them two or more gifts instead of one.
I always top up my babysitters last evening wage before christmas. My son's childminder will definitely get a nice gift, and her two other charges, my toddler's playmates, will get a toy each. My son's school teacher and Beaver troup leader, who has spent whole days with my son on camping activities, are also on my list.
I would not give a present to his drama teacher - my son only spends an hour or two with him as part of a group, and unlike the voluntary Beavers, the drama teacher is paid.
Any groups, like nursery nannies, would get a big box of chocolates to share.
