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

The double wall really keeps the water cold on our trips to the park, and the sliding lid snaps shut tight enough that I don't worry about leaks in the diaper bag. My toddler figured out the straw in about two days, and the handles make it easy for her to grip on her own.

The sliding lid is such a lifesaver when we’re out and about—no more hunting for a lost straw in the diaper bag. My toddler figured out the straw-sipping technique within a day, and the double-wall build keeps her drink cold for a full playdate.

The double-wall insulation actually keeps the milk cold through a whole playdate, which is huge for us. My little one figured out the straw-sipping in about two days, and the spill-proof lid has survived being chucked from the stroller more times than I can count.
