First of all, let children hold some toys, or make a wooden horse, so that they can have a sense of movement and match with children without being particularly bored.
Secondly, children usually prefer to play with toys. They can take some small toys such as guns or tanks in their hands, so that they won't be bored with these small toys.
I remember when I was a child, I always liked to take a small lantern or a plush toy in my hand, because little girls especially liked these small toys. If it is a boy, I will bring dinosaurs or tanks.
Besides, they can communicate more with adults. Although there are not many topics between adults and children, it is not difficult as long as they can communicate. After communicating with adults, they will know more and won't get bored.
