Things to consider:
1) Snacks do NOT have to be different everyday.
2) what will your kids actually, eat?
3) With snacks, the point is ease of eating. Meaning, do you want something that is non-perishable? Or something that will have to be kept in a cold pack? And, whatever container you put it in, can your child open it?
Most young kids, Kindergarten, have trouble opening containers by themselves. And will need help to open and close it.
4) When, are snacks eaten or what is the rules, per the school? For example: at my kids' elementary school, snacks are only for recess. And all foods brought to school has to be NUT FREE.
5) Per snacks that have to be for the "class"... well, what does the Teacher recommend? Ask her or him. There are about 10 months in a school year... thus, think of 10 snack items, that you can have your child bring once each month.
6) Per your Kindergartener: and he/she having to take a snack everyday, this year: is that for her or himself? Or for the class? If it is only for your child, then, what will your child eat, that is easy and not perishable? And can just be put in his/her backpack?
Again, snacks for your own child, does NOT have to be different, everyday.
I work at my kids' school. Some kids bring snacks. Some don't, they don't want to. It really is up to you, AND your child per what they will eat.
7) The once a month "different" snack each month for the classroom... is NOT the same as your own child bringing a snack everyday for herself. It is for herself, not for the whole class.
My kids, IF they want to bring a snack to school... is pretty much the same everyday. Because, that is what they want and request.... per whatever we have on hand in our house. No biggie.
At my kids' school, it is not mandatory, that ALL kids have to bring a snack everyday to school, for themselves.
8) per snacks for your own child: so what if it is the same thing everyday? If that is what your child will eat, fine. It is only for herself. And, don't worry about what the Teacher or others think, if you have the same snack everyday or not, for your child. No biggie. MANY MANY MANY kids, bring the same things, everyday. Because, that is what they will eat.
Some kids even bring the SAME home lunch everyday. No biggie. Teachers and staff, don't nit-pick or expect home lunches to be as varied as a restaurant buffet. I work at my kids' school, and it is really not a big deal, what a kid brings for snack or not. As long as it is nut free (per my kids' school rules) and it is not constant junk food/candy.
