The books we were reading were Higher! Higher! and Baby Happy, Baby Sad, both written and illustrated by Patricelli. My favorite of the two was Higher! Higher! The main character daughter is swinging with her daddy, pleading to go higher - and ends up higher than you would probably expect!
Both books were a fun read. The best part was certainly the illustrations - colorful and cute, they are beautiful and enjoyable. They are a bit short on story line, but the pictures tell quite a bit of story by themselves. I enjoyed asking my toddler if he knew what was going on just by looking at the pictures.
There are definitely books written by a real-life mom, and I hope you enjoy them as much as we are.
