He's doing great - gaining weight and eating and sleeping like a champ. Zoë is doing pretty well these days too - her Grandpa is here to pay lots of attention to her, so from her point of view it's all good. :)
He's doing okay at night, waking up to feed every couple of hours, as outlined in the manual. Not too bad on the parents so far, although as he's awake more our challenges will change.
Parents happy but tired. All is well.
