My three year old received this book for Christmas and it INSTANTLY became one of his favorites! It's a fun, easy to read book that points out how a military dad is just like a super hero. For our family, it helped to validate for my son why his Daddy wears a certain uniform to work everyday and why he has to be "at work" for long periods of time, among other things. While it is somewhat specific to the Army, I believe it would be an appropriate book for ANY military family, regardless of branch. If you've got a loved one who is deployed or know someone who does, it makes a GREAT gift for their family!!
