New Infantino My 1st Tumbler Sippy Cup 9 oz (Red Grinch)
The Infantino My 1st Tumbler Silicone 9oz is a 9‑ounce toddler transition cup with a soft, 100% food‑grade silicone body, an easy‑grip handle, and a screw‑on lid with an integrated silicone straw. It is designed for transitioning infants/toddlers to independent drinking at home, daycare, or on the go and fits most stroller, car seat, and cup holders. The two‑piece silicone straw includes a hidden/smart valve and soft tip to control flow and reduce spills; all parts are fully removable and top‑rack dishwasher safe, but the straw valve should be disassembled and cleaned with a straw brush or pipe cleaner to remove trapped residue.

Baby's first cup recommendations and Infantino durability
We have the Infantino My 1st Tumbler and it's been great. My 8 month old figured it out quickly and it's survived many drops. The only downside is cleaning the straw—I have to use a pipe cleaner to get in the valve area.
Comparison of straw cups and Infantino recommendation
I've tried the Dr. Brown's straw cup and the Infantino My 1st Tumbler and prefer the Infantino. It doesn't leak as much and my son can hold it easily. Just be diligent cleaning the straw or mold can grow.
Straw cup cleaning and mold issues
I had the Infantino tumbler and loved it until I found mold inside the straw valve. You really have to take it apart completely to clean. Now I use a brush every time.
