A best-selling picture book showing an alien's view of Earth babies from this award-winning team.

"Good morning, class. Today we are going to learn about Earthlets." In this way Dr Xargle, our friendly alien teacher, begins to teach his class about humans and babies. This is a hysterically funny book, with a particularly wry look at the way we bring up babies: look out for the 'egg-mangle' - will you ever want to eat egg again?
