Skye gets the front of this one. She is out ahead on a pink band of paws and hearts, Chase is at her shoulder and a third pup in a yellow hard hat is behind her, and Marshall, Everest and Skye fly across the header card above the lid. Same cup as the blue Stage 4, printed for a child who has already picked her pup.

Stage 4 is the last step on Playtex's four stage ladder, the one before an open cup, and the card is marked 24 M+. The spout is a flip up sport spout, so it shuts flat in a bag and comes open under one thumb. The barrel is double walled and insulated, which Playtex say keeps a drink cool twice as long as a cup without it, so what goes in at breakfast is still worth drinking at the park. Playtex back the cup with a spill proof, break proof and leak proof guarantee, and the card prints Leak-Proof 100%*, with the asterisk pointing to Playtex's own footnote on the pack. Holds 1 cup, 12 oz, 355 mL. BPA free.

Going up the ladder in pink, the earlier steps are Stage 1, the soft spout trainer from 4 months, and Stage 2, the straw cups from 9 months. Same cup, other pups: get this one in blue.
