Try some of the following and reap the spin-off rewards of spending time with your children. Read, read and read some more. Kids learn from your example, so make reading a part of their lives from Birth and beyond. You will probably want to buy some new books for your child's collection but there are also lots of inexpensive ways to get your hands on books. Garage sales, secondhand stores, clear out sales, friends and relatives, and the local library are some resources you can tap into.
Experiences teach children a bundle about their world.
If you live in the city, schedule a trip to a friend or relative's farm. Don't know anyone. Ask around and let your friend's know you want to visit a farm and there will be someone who knows someone who will help you out. If you live in the country, take a trip to the city for no other reason than to explore with your child. Visit high rises and ride the elevators, stop by repair shops such as shoe and bicycle stores to see how things are fixed.
