Typical sippy cup replacement parts include spouts and straws. Depending on the brand, spouts can be made of silicone or plastic and occasionally have a locking system. Straws are often standard plastic, but some contain a valve system that regulates the flow of liquid. Insulated valve systems are also present in some cups, and they often require replacement.Continue Reading
The spout is the most replaced part of a sippy cup. Parents should replace spouts when they show signs of major wear, which is typically caused by a child chewing on the spout. Any damage caused by chewing can cause leaks or present a choking hazard. Spouts that appear cloudy and sticky should also be replaced.
Proper care can help delay the replacement of other sippy cup parts. Cups with straws should have the lid removed and, if applicable, the straw detached from the lid. They can be washed in the dishwasher or by hand in warm water. Sippy cups with spouts should be fully taken apart, including any insulated valve systems installed. The base, handles, cover and lid can be washed in the dishwasher, but the valve must be thoroughly cleaned by hand, rinsed and allowed to air dry before re-assembling the cup.Learn more about Babies & Toddlers
