Carefully plan their time in the sun
Certain precautions should be taken in order to make the most of the fine weather, without going to the point of staying indoors throughout the summer, which is, of course, out of the question. Exposing kids under the age of 3 to the sun is not recommended, so think carefully about where your walk will take you, giving preference to shaded routes for sun protection.
You should also take into account the orientation of the sun according to the time of day: you can enjoy any location, you just need to avoid times of the day when the sun is at its highest, in particular between 12 midday and 4pm. Make the most of these moments to have lunch or take a nap, in the shade of course!
