Comparison of Main Materials 


BABY TRANSITION TRAINER CUP (6m+). Make weaning from bottle to cup easier with a German-made, bite-resistant silicone spout that has a breast-like feel, gentle on gums and easy to sip for early learners.
SPILL-PROOF, PARENT-APPROVED. Leak-resistant lid helps prevent messes at home or on the go, great for playtime, travel, and bedtime water.
WEIGHTED STRAW = ANY-ANGLE DRINKING. The weighted straw moves with the liquid, so baby can tip and sip from almost any angle.
EASY TO GRIP + GROWS WITH BABY. Removable handles are sized for small hands to hold and sip more independently as coordination improves.
EASY TO CLEAN + SAFE MATERIALS. Wide opening for easy filling and cleaning. All parts are removable; dishwasher (top rack) and sterilizer friendly. Made with durable PPSU plastic and no microplastic release BPA-free materials. Includes a cleaning brush for the straw.
Customers find the sippy cup to be the best on the market, with a nice design and one-piece molded weighted straw that works well. They appreciate its ease of transition from baby bottle to sippy cup. The leak-proof feature receives mixed feedback – while some say it doesn’t leak, others report it spills easily. Customers disagree on the cup’s durability, ease of cleaning, and value for money.
