Not only sleeping until noon, but sleeping through the attack and death of her child who was sleeping right next to her.
She must have been stoned or drunk or both.
I agree, gosh when the baby is week old you are tired but man o man, nerves are set on edge for every squeak from that precious bundle. Much less “sleep through” a pit bull gnawing on your baby next to you.
Stoned or drunk or both would be my guess.
