This one comes up a lot with parents of toddlers, and I always want to lead with the same thing: there is no judgment here. Sippy cups exist because they prevent messes. Most of us used them.
But it is worth understanding how they may encourage your child's swallowing pattern, because the cup a young child uses is not just a convenience. It is part of how they practice using their mouth.
Bottles and sippy cups encourage a sucking motion that keeps the tongue pushing forward in a way that does not facilitate the swallowing pattern we want to develop. The longer it continues, the longer that transition is delayed.
Open cups ask the tongue and lips to coordinate differently. Drinking from an open cup, even a small practice one with handles, is one of the early ways a child starts building the patterns that matter down the road. A regular straw can be a good middle step: it is not identical to open cup drinking, but it is a meaningfully different motion from a sippy cup spout.
None of this means every child who used a sippy cup until age three will have problems. But if oral development, tongue posture, or swallowing patterns are already on your radar, this is one of the small places where the environment at home can support the bigger picture.
Save this for a parent of a toddler who would find it useful. Check the link in Bio if you would like to learn more.
