My favorite book from Kindergarten was Love You Forever by Robert Munsch, and it has become even more dear to me since having Liam. It's such a sweet story. It's fun to read it now that I understand a lot of the absurdity of a mother crawling through her grown-up son's window to hold and sing to him. Somehow, that just seemed normal as a child!
I've also greatly enjoyed The Paper Bag Princess which I found hilarious. A fun take on the generic princess story. Maybe it's because my mom, who my dad still brags about for fixing the dryer, always taught us that women could do things just as well as men could, but I really enjoyed this book.
