Do your kids like plastic toys? Well, I guess it’s time for them to play with wooden toys. I have always liked kids’ wooden toys since I was five. I always ran along on the back of a hobby horse pretending to be a cowboy from the West when I was a little boy. Now I’m a dad and I still like buying these timeless natural wooden toys. They will never be out of style. My daughter has a child’s rocking horse, and my two sons hav e wooden trains and cars. The great thing about this type of toys is that they will last generations if they are treated kindly. Even if they break, most of the time they can be repaired using spare parts bought from wooden-toy makers, and if the part is not too complicated(复杂的), you yourself can make the part from a piece of wood. What if they do break and can’t be repaired? Well, at least they can be d ealt with without having any bad effects on the environment. They can be turned into wood chippings and used for pathways in the country or play areas for kids. Even if the wooden toy is buried as rubbish, which is very rare these days, it will not harm the soil or the environment. I like all types of wooden toys. There is such a wide variety of wooden toys today and the choice is getting bigger day by day. As an alternative(替代品) to plastic toys, wooden toys can’t be beaten.
