Kid's Cup with Steel Straw Lid
Steel cup with a stainless steel straw and a silicone lid/flex-tip - the child drinks through steel, so the only non-steel water contact is silicone.
Plastic-free verdict: Silicone only
Both the cup and the straw are 90% post-consumer recycled 18/8 stainless steel, so the child drinks through a steel straw rather than a plastic one. The straw lid itself is food-grade silicone, and the straw is topped with a soft silicone flex tip for the mouth. There is no polypropylene in the water path - the only non-steel parts touching the drink are silicone, making this one of the few genuinely silicone-only kids straw setups. Note it is splash-proof, not fully leakproof.

The Klean Kanteen 10oz Kid's Cup paired with the Kid's Cup Straw Lid. Unlike almost every kids straw bottle - where the straw is plastic or silicone and the lid mechanism is polypropylene - here the straw is stainless steel with only a silicone mouth tip, and the lid is molded silicone. That keeps the water path to steel and silicone only. Best for kids who can handle a cup form factor; it is splash-proof rather than fully leakproof, so it is not ideal thrown loose in a bag.
