ARTSCROLL CHILDREN'S SIDDUR, by Shmuel Blitz. Your youngsters-or grandchildren-are 4,5,6 years old. They are just begining to daven and you want them to enjoy the "Siddur experience"-because you know that if they love it when they are little, they will appreciate davening more and more as they get older and more mature. You don't get a child's attention with an adult page. You need a Siddur that has the look he likes, and then you can build from that to the one he will be thrilled to use as he grows older. This is a Siddur you and your child have been waiting for.
