My little guy LOVES singing the Happy Birthday song (to himself- lol). We received a box of books from one the moms in our playgroup and this was one of the books in it. I took a picture of the inside also since the cover is pretty beat up. The book is called Birthday Monsters and it’s by Sandra Boynton. It is ADORABLE! The birthday monsters come and crash the birthday boy’s big day but in a super cute, funny way (and all while rhyming). It’s sure to bring a smile! I like it because it has a lot of words that my son likes a lot…. especially the blowing out the candles part!
