Some of my and the Big Kids' (which is what I will be referring to Beck and Evie as since The Little One has arrived) books are by Shirley Hughes. She writes and illustrates this adorable seires of picture story books about Alfie and his little sister Annie Rose.
The books deal with every day occurances that resonate with little ones because of the reality of the circumstances.
Alfie locks his mom and sister out of the house after a grocery shopping trip and can't reach the lock to let them back in!
Alfie gets new rain boots and can't quite figure out how to tell the left boot from the right boot.
The stories are sweet and simple and the illustrations (my favorite part, of course!) are artistic and colorful.
