We're having another what?

Gribouille just clued into the fact that we're going to have another baby in the house. (Did he think maman was trying to look more like him? Doesn't he know only he and grand-papa are special enough to have such a round belly?) He's none too pleased with this whole second baby concept. Gribouille is blockading any access to my old car seat so the baby can't be picked up yet and he isn't letting anyone close to it until all his demands are met. Primarily, he wants a promise that there will be no tail tugging and hair pulling, no impact on his naps and he wants Belle traded in for the baby.
I'm not sure if he's joking. Maman and I are sending papa to evacuate the car seat.
