I'm still stumped...DD aged 3 has moved rooms and although she has had 2 key workers, it's quite a large nursery and the staff rotate so there's probably about 12 of them in all who are involved in caring for DD (or have been at some pint this year).
Last year I made little gift bags...some with an OPI nail polish and a fancy nail file, and others with a small body scrub/body moisturiser. I put them them all in little bags and the girls all helped themselves. It seemed to go down well.
When I've looked for ideas, most people just say chocolates/biscuits/wine...that seems so boring (and not much thought), but I'm veering towards that idea! Help!!!
