When I have a moment to relax, I usually want to use that time to read books. This is rare though, but I do make a point to read books to my son no matter how busy I may be. It is a part of his nighttime ritual, and he won't go to sleep without one. One of the most important things I feel I can give him is a love of reading. When you read books you are learning something new. Books are great for the imagination, and often help us expand our minds and our horizons. If you don't read books to your kids, you should really think about starting.
If you don't have a lot of money, you can find books that will fit any budget. Sometimes it is hard to drop ten dollars on a book, and that becomes expensive if you want to buy a lot of books. If you read books every day, you are going to want some variety. Look in discount stores for books, as there are plenty there from which to choose. You may also want to join a book club, start a book swap with some of the parents in your neighborhood, or with family members who have children near the same age as yours.
You can also read books that you download onto your computer and print out. Some will have a fee, but there are some that are geared towards children that are free. If you don't want to print out a lot of books, you can always read books straight off of your computer monitor while your child sits on your lap. This can be a great learning activity if you go online after you have read books to look up some of the things in the story. If the story was about elephants, you can do an image search and find photos of elephants to show your child.
Don't forget about your local library. They have thousands of books and they are all free for you to use. Just make sure you return them when time is up. You can read books right there in the library, and some libraries have book readings for children. This is a great place to instill a love of reading books, and will be something that will stay with them for the rest of their lives. The more they love to read books, the better they will do in school.
