The first is called Max and Milo Go to Sleep! by Heather and Ethan Long. Max and Milo are brothers headed to bed but while Max is exhausted, Milo will try everything to fall asleep. While needing lots of help along the way, Milo thinks nothing of interrupting Max's ability to drift off easily. And by the end, well, I am sure you can guess who needs help falling asleep. I checked and there is another in the series out in December called Max and Milo The Mixed Up Message.
The second is Frog and Fly Six Slurpy Stories by Jeff Mack. Check out the trailer to get a feel for this for just one of the funny stories in the book:
Jeff Mack also wrote a book called Good News Bad News that my students love. Looks like I may need a few more baskets in a few weeks when I start to set up for next year!
