1. Dust regularly - This will help prevent dirt and grime from building up on the surface of the wood and making it difficult to clean. 

2. Wipe up spills immediately - If your child spills something on the wood, wipe it up right away so that it doesn't have a chance to soak in and stain the wood. 

3. Avoid excessive moisture - Too much moisture can cause the wood to warp or crack, so be sure to keep wooden toys away from sources of water (including little hands that may have just been playing in the bath!). 

4. Store in a cool, dry place - When not in use, store your wooden toys in a cool, dry place out of direct sunlight. This will help prevent the wood from drying out and cracking.

 By following these simple tips, you can help ensure that your wooden toys will last for many years to come!
