I sit with my two-month old son on my lap, surrounded by the detritus of parenthood ā€“ burp cloths, bottles encrusted with the grainy residue of infant formula, drool-glistening pacifiers, neglected toys ā€“ and try to dredge a diversion from my battered and sleep-deprived brain. Most days something rises to the surface. A silly rhyme, a Stewie-inspired internal monologue, a popular rock song with the lyrics changed to include the infant triumvirate of milk, pee and poop. But today, nothing comes. Iā€™m an empty vessel, a vacant-eyed zombie casualty of the babyocalypse.
