Do you also sometimes have nagging children who don't want to run anymore, who want to be carried, who get bored with running? Then give them tasks, do search games and look and marvel at what there is to discover in front of you.
Starts with a walk only when the children are bored and/or they don't want to walk anymore. Children often need little incentives, because there is so much to discover.
For example, look for ants. Ants leave their traces, look exactly where the ground is loosened, the earth is sandy and very fine.
When you look closely, you see the movements and the hustle and bustle on the ground.
Wait a while to watch the ants. Do you discover an ant road?
Be careful not to trample the ants. Walk consciously on the way and look for more crawling animals.
Maybe you'll even find an ant road.
Stay curious and become a nature explorer.
