We have a great garden for kids, fully enclosed and safe, lots to explore and plenty to keep them occupied in the way of toys, balls, ride-ons etc. They are 5 and 3. They play fine if I'm out with them but as soon as I go indoors to do a job (I can still see them through the window) they moan and whinge and want to come back inside (to carry on with the moaning and whinging 🙄).
Is this normal and how do I encourage them to just go the fuck outside to play and give me a break from the whinging play independently?
