Sit down with your chatter box child and have fun asking them questions, after that encourage them to tell you a story. Even if you have no idea what they are saying, ask more questions and write down their first ever made up story. This is a great way to engage a chatter box child to be social and creative. After you finish the story have them draw a picture and make sure you label what part of the story the picture is representing. This will keep You entertained and if you love kids, you will not be able to stop laughing. Don't forget to include it in to your scrapbook.
Here is another way you can create a story using foam stickers or any stickers for that matter and have your kids play along too. This is the perfect time to encourage talking and creating a story is the best way to allow your child the opportunity to talk and tell you a story. Use the stickers as a way to create characters and or scenes in the story.
In this picture all I did was use foam letters to stick on my title and because I had foam stickers in the theme of water animals I used them in my story as characters. Making anything is about having fun, some times that's all it takes for your child to enjoy themselves. If they don't know how to write then ask them questions and you write them down even if they don't make sense. Believe me when they get older and you look back at the things you made a book at their young age will be a really nice memory.
