Helps reduce aspiration and pressure on the palate. As the baby sucks, the round structure of the pacifier widens to reduce pressure and make the baby feel comfortable. It doesnt bother babys mouth, thanks to its thin stem design. The drawings are indicative and change regularly. Please specify the gender of the child in the comments of your order. If there are any special design preferences, please mention them and we will try, subject to availability, to fulfill your request.
