No matter how it is put, plastic is made of chemicals and these chemicals can easily leach to substances within them. When does this become most concerning? When we have food or drinks inside plastic containers.

If you would like to prevent chemicals from leaching from plastic to your drinks, use non-leaching containers such as stainless steel.

Try These:

Klean Kanteen – Stainless steel water bottles and sippy cups. Great for warm and cold drinks.
Disadvantage: One design (but they did just release new colors).

Sippy Cup

Sippy Cup

Sippy Cup

Sigg Cups – Aluminum water bottles and sippy cups that come in cool designs. You can get a “Kids Grip” accessory for easier handling for babies/toddlers.
Disadvantage: Have to wash them by hand; not dishwasher safe.
