Maple is a light wood with a pleasant grain, resistant to stress and wear. It is used, for example, to make musical instruments (which could be included among toys). I would suggest any type of hardwood, such as oak or maple. In my opinion, softer woods such as spruce pine or spruce are more likely to chip and that would not be good for your little ones.
Make sure you sand everything you do thoroughly to make it smooth to the touch. Make sure all the dust has been wiped off. You can use lemon oil to coat the finished product and give it a clean shine. It would avoid stains and lack of color on children's toys, as they can put the object in their mouths and there are many chemicals in wood finishing products.
As a parent, I made sure that my son didn't have any problems with the materials he used in all his wooden toys before I gave them to him. However, the sense of hearing is well developed, so all kinds of rattles or wooden music boxes (of course, with moderate sound intensity) can arouse the child's curiosity. These reddish woods can be used for the creation of toys, for example, to obtain pawns for board games such as chess, checkers, backgammon and others. I am a student at GCSE and for my exam I have to design a toy for children and I wanted a durable, non-toxic and cheap wood for some of my designs that could be thrown away and placed in children's mouths without being damaged, but I really have a hard time finding one since different websites have different information.
The stable straight grain does not have strong characteristics, so its wood is often found in non-glamorous applications. Fruit woods and those that come from trees that produce nuts such as walnut fall into the category of food-safe woods. If you are going to make toys for children, you have the option of using softwoods, hardwoods or artificial wood. Therefore, we can conclude that there is no toxin in beech wood that contributes to another factor that makes it suitable for children's toys.
Hardwoods: No matter what wood is used, hardwoods are always one of the safest bets to keep wooden warriors happy for years to come. Whether chewed on young children's teeth or stepped on by older people, hardwoods are dense enough to bite and damage a foot, while remaining fit for future generations. The best in beech: one of the most common materials of manufacture among different types of toy-safe wood, beech is an incredibly durable material. But I would say that your wood quality standards are higher than the average consumer (like you and me).
No matter the material, it is the FSC that determines the highest quality when it comes to the safest wood for children's toys.
