AIBU to ask what the norm is for teachers' gifts end of term?

[Cantaffordthetherapy]

Yesterday was my son's end of term at preschool nursery (not school run if that makes a difference but free hours - not an especially affluent nursery). I bought a nice tin of posh biscuits for his keyworker (sort you can keep and reuse the tin for) and have only ever bought chocolates etc at Xmas etc. I noticed someone turning up with a MASSIVE hamper of something (food or smellies) and at the end of the day noticed there were about 3 such gifts. Is this the norm? Am I going to be the stingy parent?
I don't know if it was perhaps people who have children leaving for school (mine isn't) or one extravagant individual who bought for all (I just got keyworker) but I didn't do anything so extravagant when my daughter left.
Was planning on the same gift each for my daughter's two teachers at the end of the week at school - one of whom she has genuinely loved to bits and will miss. She's done a little personalised card for her too. Now I'm wondering if I'm going to look mean!
My mum used to be a teacher and she'd always come home loaded with gifts at the end of term but it was never anything more than boxes of smellies or chocs or the occasional bottle of wine.
AIBU to think these gifts are a bit OTT?

The only time I have bought presents is at the end of nursery (end as in both my boys had been through it) when I bought all the nursery staff a bottle of wine each.

I never bought anything at school, but I did say thank you regularly and volunteered to run an after school club (thereby saving one of the teachers from doing it).

I am buying a hamper of biscuits and some books for the nursery but both my children are leaving and I have used them for nearly 4 years and I want to get something for all the staff they have been involved with over their time there.

Their keyworkers are getting a card, as well as a card for the whole nursery.

We clubbed together and got the nursery a piece of equipment they wanted. So in a sense it was more for the children than the adults, but they got the 'thank you' gift and appreciated the gesture I think...
