Sweet! The illustrations of the monarch in all its stages are superb (The one of a boy's face less so. People are the hardest to draw!), and the text is simple and quick enough to read with a squirmy little one.
I liked the extra facts at the end, although, having raised a couple Monarchs, it doesn't take "about 2 weeks" ala Eric Carl, it's 10 days.
Definitely worth the download.
