This Best Selling Baby Aspirator is perfect for ears, nose and airways to keep them clear from mucus and congestion while helping with infections. Gentle enough to use on infants or toddlers. Suction is enough to clear passages but will not hurt or harm blood vessels. Ideal for baby registers and to keep on hand for baby's first cold. This is reusable but must be cleaned properly. Clean the syringe after each use by suctioning up warm, soapy water. Shake it around the bulb multiple times. Follow with plain water and squeeze out as much as possible. Let dry thoroughly by standing up, tip down.
