WeeSprout 3-in-1 Stainless Steel Cups for Kids are the perfect step up for little ones learning to sip like big kids — without giving parents a reason to stress over spills. These ultra-durable cups are designed to grow with your child, functioning as smoothie cups, food containers, and on-the-go snack jars.

Designed with speech pathologist recommendations in mind, each cup includes a curved straw with an open valve to support healthy oral development and proper jaw alignment — ideal for kids transitioning from a sippy cup to an open cup.

Soft, food-grade silicone straws are gentle on gums and teeth and ideal for thicker drinks like smoothies. Built-in straw stoppers keep straws in place — no more flying messes or sticky hands.

Each set includes both drinking lids and storage lids for maximum versatility. Protective silicone sleeves provide grip, help prevent drops, and insulate cold drinks to keep little hands comfortable.

Available sizes:
8 oz cups measure 2.88" W × 4" H
12 oz cups measure 2.88" W × 5.5" H
Recommended age: 3 years and up (use with adult supervision)

My toddler finally stopped knocking over her sippy cups since these are weighted just enough at the base. The 3-in-1 lids mean I'm not buying separate cups for every stage, which honestly saves me cabinet space. Stainless steel also means no lingering milk smell after a day in the diaper bag.

I've washed these four cups probably twenty times already and they still look brand new, no rust spots or scratched-up coating like our old plastic ones. The stainless keeps water cold through a whole afternoon at the park, which surprised me. My 4-year-old finally stopped asking for a sippy lid.

The set of four is perfect for rotating through the dishwasher during the week, and the 8 oz size feels just right for my daughter's little hands. I love that they're stainless steel, so I don't have to worry about the plastic taste or hidden scratches from her roughhousing them around.
