Our schools don't have very many rules. We are kind of a small town. 25k residents. My kids school has 600 students and there is no policy about not being able to drop anything off for the kids. About once a week my son forgets to take his medicine in the morning and he will go to the office and call me and I drive back up there and take him his pill and the office just calls him to the office and I give him the pill and a bottle of water and leave. It is partially his fault and partially mine. I remind him (most mornings) to take his pill after he eats but sometimes I forget to follow up and ask him if he really took it or not. Those are usually the days he forgets. He is only 10 and doesn't have a fully functioning organized brain like some older kids might. He is good about keeping up with all his school books, homework, folders, etc. Last year he called me to bring in a library book he forgot at home that was due back in that day and it was his day to go to the library. I took it. I didn't mind.
Our school has lunch accounts where you put money on your kid's account or they get it reduced or free if they qualify, but you put money on it and if for some reason you forget to load it they will still let the kid get a lunch and the account goes negative until you put more money on it. They would NEVER turn a kid away and tell them they couldn't have a lunch. I would be horrified if they would do that to any kid. And for a parent to refuse to take their kid a lunch they forgot just to teach them a lesson is pathetic. Trying TOO HARD to push your kids to act like adults isn't any better for them then coddling them and babying them. Anybody can forget or make a mistake. And YES ABSOLUTELY 7 hours is WAY TOO LONG for any kid to go without food. You may go 10 hours at night while you are asleep but that is what our bodies are built to do. Our brains and organs shut down, our metabolism shuts down, there are no processes running that require calories, so comparing sleeping to going awake all day without food is just not very intelligent. Think about that one a little bit. They are not even the same thing AT ALL. I do feel sorry for kids with parents like that. Especially if they see how loving their friends parents are if they forget something and get it brought to them and then to know OH WELL MY MOM WON'T BRING ME ANY FOOD I am just S.O.L. That's sad.
Our school makes the kids put the backpacks in their locker after they take their things out of it for the day. But there is no rule about the backpacks being clear or mesh.
Our school allows water bottles of any color and they do not restrict what the child has in it to drink. They do not tell us it has to be water. It can be juice or Coke or whatever you want them to have. Mine don't usually take a water bottle just because they don't like keeping up with it. But I am glad they give them the option. Kids should have more than just 5 or 6 ounces of water at lunch time. If they are in school for 7 hours they should have a few ounces of water every hour or two minimum to stay hydrated.
Our school allows hoodies or any kind of jacket and they SAY it has to be school colors, red, khaki, blue or black. But they don't enforce that. My daughter has a black hoodie that she wears but my son's light jacket is brown and he wears it every day because it stays so cold in the school. He doesn't have a jacket that are school colors. He wears what he has. Nobody says anything.
All of our district's schools have a zero tolerance policy on weapons, alcohol and drugs.
And the one my DD11 hates, no unnatural hair color. She wants a pink stripe in her hair so bad she can't stand it but they have that rule all the way through junior high and high school, so she just can't do that to her hair, unless she just does it for the summer and puts it back before school starts. I am not sure I would even let her. It's not an issue yet.
OH, they do have a rule about no open toe shoes, but that is just for safety reasons. I get that one. No sandals or flip flop. Jeans and pants can't have rips or holes in them, not even the kind you buy that way on purpose.
Uniforms shirts are suppose to be tucked in and all students are suppose to wear a brown or black belt. They don't enforce that one either. Hardly any of the kids actually tuck and most don't wear belts.
