Your kids will love toys, and they are really useful for stimulating them, keeping them out of trouble, and finding their likes and dislikes. Try and have at least one toy per kid and a designated area for toys only. If their status is playing, drawing, or dancing with said toy, you should try and praise them. Don't praise too much or they will say you are nagging. Don't leave toys on beds or chairs because then it is harder to direct them towards it. Have a variety so as not to bore your kids.
