There's a reason Olivia has known her ABCs from the moment she could speak, and was humming the tune to the Alphabet song even before that. We sang her the famous letter song through every diaper change from infancy to age 1, and had a banner with all of the letters of the alphabet right above her changing table.
We've since moved and I have no idea where that banner went. Maybe it's on strike somewhere from being overworked... But I absolutely LOVE this Alphabet Poster from Children Inspire Design. It is printed on 100% recycled paper with soy ink, and wrapped in eco-friendly packaging. So babes can learn how to spell g-r-e-e-n from a young age as well.
