We Just Had A Baby [PDF ebook] 

It’s not easy getting used to a new baby in the house. Everyone in the world thinks whatever the baby does is amazing! And if you aren’t the baby, everyone acts like you’re invisible. This clever, funny picture book is told from a slightly older sibling’s point of view. The observations about living with a new sister or brother are poignant, spot-on, and will make even the youngest reader chuckle.
