That wasn't specified at all but I will ask the teacher. I do know that they're still allowed to bring in cupcakes or cookies for b-days with teacher approval. I don't see how this would be any different.
A little off topic but not really. You know what I'm really disappointed with is the lack of parental involvement. When I was at open house we brought with us the school supplies that were on his list. There was a note on the chalk board that said the classroom was also in need of supplies, there were post-it notes below with various items such as napkins, paper towels, etc. and that if you wanted to contribute to take a post-it note of the item you'd like to bring. ONE other parent took a post it note. ONE out of a class of 22 students. I took 3 off before we left; paper towels, napkins and hand sanitizer. Now, good Lord, if I can afford the whole $15 I spent on those supplies on one income, with two kids than I'm sure other parents could have picked up at least ONE $2 item. Anyway, after what I saw there I'm fairly certain that there won't be much parental involvement in bringing in snacks for the class either.
I'd like the kids to really enjoy their snack.
