I sell Usborne Books, and before Eleanor was born, I purchased a few books to help with the transition (and to keep the girls busy).
A set that I purchased was the sticker fairy serried (both little and regular, for Jennifer and Hazel respectively). Today, I pulled them out! The girls are loving them them and I love that that are re-stickable! So they can go back and change their friends (or back drops) later.
The girls think they are just having fun, but they are working on fine motor skills – distraction learning for the win!
