17 May is one of the loveliest days of the year. Flags, marching bands, children's parades, ice cream, and proud families in traditional dress. But behind the celebration are some real safety considerations for the youngest children: warm spring weather can surprise you, crowds can be overwhelming, and a day full of impressions can drain a little body faster than adults notice.
This guide gathers the most important points for a safe 17 May celebration with children, from sun protection to what to do if you lose your child in a crowd. It supplements our main guide on the 17 May hub, where you will find all articles and checklists collected.
Sun and UV protection
The May sun in Norway is stronger than many people think. Even when the air is cool, UV radiation in the middle of the day can be as high as in July. Young children's skin is thinner and more vulnerable than adults'.
Sunscreen and age
Sunscreen should not be used on children under 6 months. For babies under 6 months: keep the child in the shade, use clothing and a hat. Sunscreen can be used from 6 months of age, with SPF 30 or higher — preferably 50+ for children. Source: helsenorge.no (17.04.2026).
For babies under 6 months, sun protection is about physical shade: a parasol on the stroller, a sun hat with a brim, light long-sleeved clothing, and deliberately choosing a shaded spot. Do not rely on the stroller canopy alone to keep UV rays away — sunlight reflects from asphalt, walls, and light-colored clothing.
For children over 6 months: use sunscreen with SPF 30 or higher, preferably SPF 50+. Apply 15–20 minutes before going outside, and reapply every two hours. Remember areas that are often forgotten: ears, neck, backs of hands, and feet if the child is wearing sandals.
Sun hat and clothing
- A sun hat with a brim all the way around protects the neck and ears better than a cap
