I drink water with all meals and in between meals. I drink milk a few times a day now that I'm pregnant, but that's it. I occassionally drink tea when we go out to eat, but not when I'm pregnant. DH drinks Dr Pepper with all meals.
In the South here and where I lived in Texas, dinners at school and church usually just serve sweet tea and water. If it's an event that's targeted to kids, sometimes they provide punch, but a lot of parents don't see anything wrong with giving even the tiniest kids tea.
