"Hey, Archer. Guess what! There's a baby in Mommy's body!"
"Baby?"
"Yeah. Right in here. In my belly, see?
"No baby, Mommy."
"Yes, baby. Just really small baby right now. Grape-sized."

Archer flashes me his "what the hell kind of drugs you on, woman" face
"Do you want to have a baby?"
"No!"
"You don't want to have a little brother to wrestle with?"
"No!"
"Do you want a little sister to play with in the park? You can frolick and--"
"No!"
"You don't want a little friend to build forts with and draw on walls with and--?"
"NO! NO! NO! NO! NO! NO! NOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
"You know what? When you have a baby you get ice-cream. All you can eat ice-cream. And cookies."
"Ay-Keem? Yay! Ay-keem!!!! Yay!"
"So do you want to have a baby and cookies?"
"Yays!"
"Do you want to have a little brother to wrestle with and ice cream? "
"Yays! Ak-keem baby!"
"What about a baby sister to push on the swings and cookies?"
"YAYS! YAYS! OKAAAAAAAY. Coo-KIE COO-KIE. YAYS, MOMMY! YAYS! Wheredigo-Ak-keem-COOkie?"
So I'm really happy to report to all who've enquired that Archer can't wait to be a brother. And ice-cream. And cookies. And... yeah.
