This book is wonderful, and I highly recommend it. It's wonderful to have a book about families that I am comfortable reading to my son, who came into our family through adoption. So many books make assumptions about "normal" families, and this one does a fantastic job of including all families without any expectation of being "normal." This book helps to give my son a framework for understanding the world in which he lives. He will encounter friends whose families are in each of these situations. The colors are striking and fun, and my son loves to look at the pictures.I see many reviews that have trouble with the mention of same-sex parents. Evidently these parents haven't stepped outside and opened their eyes to the world around them, and would prefer to pull blinders over their children's eyes, as well. Clearly, this is a reality in the world, whether you choose to read your children a book that acknowledges it or not. If your children attend school, or leave your home, they will encounter families with two moms or two dads. No matter how hard you try to "protect" them from this reality, they will soon discover it - you may as well read this book and process this with them. (I, too, am a "religious fanatic," as one other reviewer mentioned, which is why I am a pastor of a congregation that is fully welcoming to all, and welcomes LGBTQ-identifying folks without any expectation of change. Gender and biology are never sinful. Being a part of a loving family is never sinful.)Also - no. This book does not require you to have the "birds and the bees" conversation with your kids just because it mentions same-sex parents; if your child doesn't understand how sexual intercourse between opposite gender parents works, they will not be concerned about the biology of same-sex parents birthing a child. That question simply isn't on their radar. Tell them the truth - that sometimes families are made of two moms or two dads. It's a fact. I would suspect you should have even more difficulty explaining spontaneous reproduction by a single parent? As a parent who has a child through adoption - please DO normalize families who have children without having given birth to their child.Acknowledging the world as it is is NOT an agenda. It is reality. To have not included all types of families into this book would have been a major disservice to Parr's tiny readers and their families.Kudos to you, Todd Parr.
