Make the big ones small again!

What if parents became children again for a while? My parents have no time for Kuba and Luka. But that changes when the children receive a magic bell from Alfons the elf! Just ring the bell and say the incantation, and busy parents start playing like children again... Which, in the middle of a big shopping trip, on the playground or on a castle tour, causes a number of funny and absurd situations. From the author of the successful book Christmas at the Door.
