This set includes 3 standard socks which wrap snugly around your baby’s foot. Each washable sock connects to a central base station, up to 100ft away without wires. Owlet Socks fit most infants from 0-18 months or 6-25 pounds and should be hand washed regularly and alternated from right to left foot each night. BPA free, latex free, lead free.
