These children are preschool children. They're prone to being spontaneous and excited, but still very sweet and lovable. They are enamoured with their new substitute and like to have fun playing with him, giving him lots of attention. If you would like to ad lib some lines for them, feel free. There are a lot of scenes where they will be talking over each other in the background. There are about 15 children but only 5 main ones, so try as many different voices for them as you'd like.
