I recently purchased a custom printed CamelBak Eddy kids tumbler for my daughter to use for school. It is a .4L bottle and is perfect for a 5-year-old.
She loves the cool colors (we got berry) and I love that is BPA FREE, easy to clean, child safe, and has a simple stem and bite valve straw. I originally gave Vika a regular bottle of water (Poland Spring) and I feel that it was just too heavy for her backpack, especially since she can't drink the whole bottle in the few hours of Kindergarten.
I would definitely recommend this bottle to anyone with children. Even with the straw upright, the bottle is spill proof. Love it!
