Care of the Uncircumcised Penis
The uncircumcised penis of a newborn does not require any special care. The American Academy of Pediatrics states that "it is not necessary to retract any part of the foreskin in order to wash under it." External washing is sufficient. Wash the penis with warm, soapy water just as you would any other part of his body.
Do not retract (pull back) the foreskin. The foreskin and glans (area covered by the foreskin) will separate normally over time with growth and development. For some boys, the foreskin will retract while they are infants and for others, it may take as long as five years. Trying to pull back foreskin that is not yet ready to separate can create tears and scarring. It is best to let your baby's health care provider assess if the foreskin is ready to be retracted during your son's well baby check-ups.
