Rinse off before and after swimming: You have to rinse off your baby before and after swimming to remove extra chlorine and other chemicals from his/her skin. 2. Apply a moisturizer: Always apply a baby's skin-friendly moisturizer after swimming to keep the skin hydrated. It should be specifically for after-swimming use only. 3. Dress in protective clothing: Carry some clean and dry cloth along. And dress your child in dry clothes after swimming to protect his/her body from the sunlight. 4. Avoid prolonged exposure: Try to limit your baby's exposure to the sun and in the pool, especially in the peak hours when the sun and the chlorine are strongest. 5. Use baby-friendly products: Make sure that all the products that you are using on your baby's skin and the diapers and toys are specifically designed for use on babies and have no harsh chemicals. If you have any concerns about the effects of chlorine on your baby's skin then it is best to consult with your doctor about it.
