present etiquette at day nursery

[ImpatientGriselda]

This is DD's first Xmas at her lovely day nursery; she's looked after by a "key carer" and 2 other main carers (who I see just as much as the key carer). On top of that there are the very sweet nursery mgr and administrator who all muck in. Help - is there an etiquette about who to buy what for? Pressies for everyone, or just for key carer? And what sort of pressies will they (possibly) be expecting? I don't want to disappoint anyone by getting it wrong...

Big box of choccies or biscuits for them all to share?

My DC go to a small nursery with only 15 kids, there are 5 staff. I used to do big box of chocs but then so did all the other parents. So this year I will be sending in 5 bottles of wine instead - I know what I'd rather have!

heck, I didn't even think about this til I saw it on here. Another present I have to get..didn't get one last year as it didn't cross my mind.
Just realised I had just found out I was preggers with DD this time last year and thought it was another ectopic so no wonder it didn't cross my mind. Will have to make it a extra big box of chocs/biscuits.
