Hello. My little boy loves books. I have saved up some money to buy him some special books for his first birthday since we only have a few of our own. Can anyone recommend some really special books that a one year old may enjoy now and preferably in the years to follow? We don't have much spare money this year so I want to make sure I spend the money really wisely. He already has We're Going on a Bear Hunt, Dear Zoo and Each Peach Pear Plum, all of which he loves. Thanks.
