It is a good book, like all T'choupi. For cons, I have not yet given my 3 year old daughter who has trouble making his nap, because I think the moral is very subtle. In short, T'choupi is at school and does not want to nap. After a while, the teacher allows him to leave his bed to go to the reading room ... where he fell asleep, just when his comrades wake up! Is it really encourages children to nap? In my daughter's school, they do not have the right to get out of bed to force them to take a real rest time ... and my daughter fell asleep in bed! At home we can not do.
