This pacifier is really amazing! It helps my daughter to be soothed, it is great for use while she is sleeping, and very easy to clean. Also it helps with ventilation of air so that no rashes are formed. The nipple is designed in a very strategic design so it doesn't pose as a harmful substance for hazard or for mouth development. Love the design of the pacifier and will continue to use this brand. Overall, I would totally recommend this pacifier.
