It's my first time. No one seems to be starting group gift. Small school, my daughter goes 3 hours/day 5 days/week.

What is the appropriate amount to spend? Am I supposed to get a physical gift, a gift card, or just give cash?

My only thought so far is to write a letter about the positive changes I have noticed in DD1 (starting to read, loves going to school, etc). Maybe with a gift card? Coffee or something...
