Babies under six months must not be exposed to the sun, at all. And don't use sun block until the baby is at least a year old. Babies should be put in the shade and kept out of the sun.
Be careful with sunscreen
Since your baby’s skin is immature you shouldn’t use sunscreen until your baby is at least one year old Instead, protect their skin with airy cotton clothes and keep them in the shade It's a good idea to have a sunshade available
Never expose your baby to direct sunlight It's best to avoid sunny places, and be careful about indirect sunlight that reflects off water and sand – even off a white sun umbrella
If you're unsure about sunscreen, clothes and outdoor activities, talk to your nurse or doctor
