Big Kid Straw

Upgrade your Little Stackers sippy into a proper big kid cup! This straw is wider for more gulp, rigid (not weighted), and made to fit perfectly into our sippy lids. Think of it as the low-fuss, ready-for-anything sibling.

Perfect for water (like a real drink bottle), smoothies, or thicker formulas — just skip the chunky bits, because the clever tip still has our gentle valve to help prevent spills. It’s not a totally free-flowing straw (no floods here), but many families find it easier than most on the market. Every bub is their own little character, though — what’s effortless for one might take a little practice for another.

Weighted straws are fab when you need them, but this one’s the low-maintenance big sibling. No fiddly parts, no extra cleaning — just a solid, satisfying sip.

For little legends 6 months and up!
