Dr. Brown’s Milestones™ Geïsoleerde Beker met Rietje, 2-Pack

My toddler’s drinks stay cold for hours thanks to the double wall insulation, which is perfect for long park mornings. The spill-proof lid has survived being thrown from the stroller more times than I can count, and it still doesn’t leak a drop.

The sliding lid is a lifesaver when my toddler decides to practice her throwing arm mid-sip—everything stays contained. Water stays cool for our whole morning errand run, which is a win for a kid who hates warm drinks.

The double-wall insulation actually keeps the milk cold through a whole playground trip, which I didn't expect from a sippy cup. My son figured out the straw on his own within a day, and the spill-proof lid held up even when he tossed it out of the stroller.
