Newborn babies do not need to be bathed every day and plain water is enough to keep them clean, skin experts have said.

According to a team of US dermatologists, giving a bath to a newborn baby can be intimidating for new parents, as the infants are vulnerable and can become very slippery when wet. Parents can also feel overwhelmed at the amount of bathing products that are on offer.

As proper skin care is so essential for infants, the dermatologists decided to carry out a review of the best tips for keeping little ones clean.

They pointed out that newborn babies are ready for their first bath once their body temperature, heart rate and breathing status have all stabilised, which is usually around six hours after their birth.

However, newborn babies do not need to be bathed every day. Every few days is enough to keep their skin clean. In between bath days, the skin should be gently wiped with a damp facecloth.

When having the bath, plain water is enough for the child. The dermatologists pointed out that the skin of a new baby is susceptible to irritation and infection. Where products are used, they should be mild and contain no fragrances or dyes. Such products should not be used often and should be washed off completely.

The baby should be completely immersed in the water, except for their head and neck, as this will help keep them warm. Always make sure the baby is properly supported and ensure the water is not too hot.

The dermatologists also recommend changing a newborn's nappy every two to four hours or after they have soiled. The best thing to clean the baby with is tap water and a soft cloth. If using baby wipes, choose hypoallergenic ones that do not contain alcohol or lanolin.

If the baby develops nappy rash, the dermatologists suggest using creams containing zinc oxide, which act as a barrier between the urine/stool and the skin.

If this does not clear up the nappy rash, the baby should be seen by a doctor.

The dermatologists offered their tips in the International Journal of Dermatology.
