Wonderful book reassures little ones we are always with them, somehow
Format: Hardcover
Purchased this book for my 6 year old grandson, whose family will be moving out of state within a year. This is a wonderful, touching books that lets children know that you are always thinking of them, loving them, and always there. My grandson can read the easy words and short sentences by himself, or have his parents read them to him. Very, very cute ways they relate everyday occurrences to us being there for our loved little ones. I highly recommend this book!

Reminds children they are loved by looking at nature!
Format: Board book, Format: Board book
This book is so great! I love how it reminds children that they are loved by simply looking at nature around them. For example: "That inviting ocean? That's me waving at you. That clap of thunder? That's me raving about you." So cute! The opening pages and closing pages show a mother & son together, but the in between pages show boys and girls. I kind of wish the cover wasn't so obviously a boy and his mom since I have a daughter, but it doesn't stop me from reading it to my kiddo. All in all, five stars! :)

Great for reading with a small child.
Format: Board book
I read this every week from Oklahoma to my great granddaughter in California. The story is perfect for our situation, the cardboard pages are easy for her to turn the pages and that makes her feel like she is participating in the ready. Beautiful pictures and well written verse. We love it.

SIMPLY A TOUCHING, LOVELY BOOK FOR ANY AGE!
Format: Hardcover
This book is beautiful in every way! It expresses the deep, unconditional love parents have for their children. The message could be beneficial for children who have lost their parents or who don't see them every day. Or, it can be a simple as...these are the ways you can remember I love you when we're separated for the day! I purchased it for my daughter who just graduated from high school. I plan to give it to her on college move-in day. Reading it brought tears to my eyes, but it has such a special meaning. BUY THIS LOVELY BOOK WITH CONFIDENCE!!!
