I don't think it is child abuse if the parents are being cautious about having too much, but if the parents are forcing them into eating it, then i think it (might) be. I don't think using child abuse to explain this situation isn't really relevant though, you could say it's not healthy or too much, but I think using these words to describe this situation is not correct. If the parents are forcing you to eat healthy foods, then you shouldn't blame them. But if they are FORCING you to eat / drink unhealthy foods, a.k.a soda, bagged chips, etc. Then you should just say no to them. I would most likely say no unless they are forcing you.
Marching band is a little more intense than concert. in marching band your outside and you are marching to a certain piece of music except they are called movements. in concert you are siting most of the time and concert in a lot more formal.
