Check around at your local cheap shop for a 100 to 150 page coloring activity book and then carefully tear out the pages or cut them out. You will then see that this will give you one page with two pictures on it front and back. Get your child to pick through the pictures until they find one that they want to color in and let them go to it. When they have finished that picture turn it over and get them to color in the other side of the picture. This will keep them entertained for ages if they are tempted to just color one color then encourage them to make it more colorful because you something special planned for their picture once they have finished but they need to make it colorful.
You can create your own book full of simple coloring pages. You only need enough strong quality paper and a creative eye to sketch the images. The images should have thick lines to show distinctive features. You can make coloring books of the alphabet, nature, numbers, the world and countries, animals or cartoons. However, you should keep in mind that the book should not only be a fun filled coloring thing but an educative tool too. In addition, keep it go for simple shapes that even the toddler can try to sketch.
One of the most enjoyable things I can remember from my childhood is my love to draw and color and I see that with my own kids now as well. My little girl especially loves to color and of course most things should be pink. Coloring pages for girls specifically will give little girls pictures they will love to color so they can enjoy this wonderful creative activity. Of course this will include many princesses and perhaps dolls, puppies, teddy bears and kittens. Basically I think it comes down to anything cute.
