You won't get vitamin D from the sun if you wear sunscreen, but you should apply sunscreen with a sun protection factor (SPF) of at least 15 before your skin starts to turn red or burn. This will help protect your skin from sun damage.
While it's important for children to spend time in the sun to prevent rickets, babies and young children have very sensitive skin that burns easily. They need to use stronger sunscreen and be covered up when out in the sun.
In the UK, your skin isn't able to make vitamin D from the sun from October to early March because the sunlight isn't strong enough. However, you can get vitamin D from your body's stores and from food sources during this period.
