I read the title out loud and my wife said "Like the transfusion syndrome?" (Twin-to-twin Tansfusion Syndrome is a condition with identical twins where, in the womb, one twin takes more resources than the other. It can be very bad.) So I almost stopped reading right then.
But I gave the book a try. It's more a book written for parents though. "Double the diapers, double the messes." It states the obvious and doesn't add anything to my twins' experience.
The perfect book for your twins or even an older sibling, waiting for twins in the family. Sweet rhyme and adorable illustration. I bought it for a friend recently and she said after all the non-fiction books on twins she had read over the last 9 months, this was a total joy to read and her 3 year old daughter loved it.
My mediocre review may be due to looking at this through an adult's eyes rather than a child's. I believe children would enjoy the cutesy pictures and the rhyming text.
What draws children the most is a rhyme scheme and a repetitive word. My five year old loved the rhythm of words that she helped me read whenever we saw the word "double". The book helped her learn a new word as well as get a feel for rhythm in the written word.
