Puzzles are one of the items that are not just used to enhance certain skills with kind, but are also used to test intelligence. Because of that reason, it may be important to offer your child the option of playing with such puzzles. Granted, puzzles become a lot more useful after the first year of the child, but simple stacking puzzles become quite useful early on.
Child development should include a variety of puzzles and on the other hand, also creative toys (such as LEGO’s). With these toys your child will learn how some things are pre-determined, while others are more sandbox-like.
