transition cup

Transition cups are made from materials such as plastic (including polypropylene), stainless steel, and silicone, depending on the model.

Most transition cups list suggested ages of either about 6 months and up or 12 months and up, depending on the cup’s design and drinking mechanism.

Designs that simplify cleaning include straws that peel open for access, fully removable parts, lids that tuck the straw away, and cups with fewer components; many models also include a straw brush.

Common options are fixed or removable handles, side grips, and contoured bodies that are sized for small hands—these help toddlers hold the cup securely as they learn to drink independently.

Features that ease the switch include weighted or flexible straws, easy-grip or removable handles, soft silicone spouts or spoutless 360° rims, and spill-prevention lids (flip-top, sliding, or self-sealing) to support independent holding and sipping.

Most listings show capacities around 7–10 ounces. Examples in results include a 9 fl oz (US) cup and a 20-ounce capacity noted for a two-cup set.
