One of the best things you can do to stimulate your children's development is to read to them daily. Even starting in early infancy can be beneficial. Not only will it help your child develop the skills needed to enter kindergarten, but it is a great way to spend time with your kids. While on this subject, I'd like to make everyone aware of a wonderful organization that helps make reading to your children easier. Dolly Parton's Imagination Library is a non-profit organization that will mail a children's book to your house every month from birth up to 5 years. It's completely free and an excellent way to start your own little library at home. To sign up, you can go to the Imagination Library website to sign up.
Remember, read to your child early, and read to them often!
