Good for oily people
Style: Soap Saver
This absolutely gives me a ton more lather than the bar by itself, and the rougher texture feels nice, like I'm getting a deep clean.

Meaningful and poignant read aloud, especially for children who have lost their moms
Format: Paperback
I bought this book to read to my class last year. It was a meaningful book, especially as there was a student who had lost her mom last year. I had a hard time getting through it because it was so beautiful and well-written.

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!
