Today we are going to learn about Earthlets."</b><br><b></b><br><b></b>In this way Dr Xargle, our friendly alien teacher, begins to teach his class about humans and babies. </p><p> 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?</p>
