Sweetest book!
Format: Hardcover
I think this is the cutest little book and it makes a perfect gift for dads! Especially first time dads or dads that are having a first time daughter. Great for a gift for Father’s Day, gender reveal, or just to gift dad in general! It’s a sweet story to read and dad and daughter will both love it!
