Ripple Kids 隨身原味牛奶（12入）

The 8g of protein is solid for a kids' drink, and my daughter actually finishes the whole carton without a fight, which is a win. These are my go-to for packing in her lunchbox or tossing in the cooler for soccer practice.

The 8oz cartons are perfect for shoving into the side pocket of the backpack without any leaks, and my son actually finishes them at school. Having 8g of protein in there makes me feel better about the days he skips breakfast.

My kid's lunchbox finally comes home empty—the 8oz cartons are the perfect size and the 8g of protein keeps him full through afternoon practice. He actually asks for these over juice boxes now, which says everything.
