Guides that work through what these do, written for the stage you are in.
Replacement parts, and keeping gear in service
Straws, nipples, spouts, lids and pads. These are the pieces that wear out, get chewed through, or vanish into a dishwasher basket, and every one of them is sold on its own so a cup or a bottle does not have to be replaced because one part is missing. Sizes are specific: a part is made for a named piece and the product page says which.
How do I know which straw or lid fits my cup?
Match it by the cup, not by the look. The 5oz training cup takes a snap on lid, the 11oz tumbler takes a press seal lid, and the two are not interchangeable even though both are straw cups. Each replacement part page names the pieces it fits. If a part is not listed for your cup, it is not the right one.
When should a silicone part be replaced?
Replace a nipple, straw or spout when it has a tear, a split at the base, a hole that has widened, or a permanent change in shape after washing. Discolouration on its own is usually staining from food and is not a reason to bin it. Anything a baby chews on deserves a look every few weeks.
