Straw cups are fine to offer to baby from around 9 months of age or earlier if they have the skills to drink from them. This new feeding bottle trains the baby to suck using the straw that is inside. When sucking, it generates a vacuum that makes the milk/liquid flow, favoring the development of the baby’s facial muscles. The child sucks, swallows, pauses and breathes following a natural and individual lactation rhythm. The small straw is actually the reservoir of a powerful internal vent system that’s clinically proven to reduce colic, decreases spit-up, burping, and gas. Your baby maintains a natural behavior when sucking, forming a vacuum that allows the liquid to flow continuously, training their facial muscles, breathing and establishing pauses following their needs at all times.
