My kid would either struggle with the lid until she threw it across the room, or pop it open and dump water down her shirt. These are the ones she figured out on day one without a single spill.

I once took apart a kids bottle and found something growing inside the straw that I'm pretty sure was alive. These are the ones where every single piece comes apart for real cleaning.



















My son has a talent for launching things off tables, out of strollers, and onto concrete. These bottles took the abuse and kept working without cracking or losing their seal.

















Half the battle is getting them to pick up the bottle in the first place. My daughter ignored every plain bottle I bought until I let her pick one with characters on it. Suddenly she was hydrated.
