But the baby itself can only get attention for 24 hours per day. I think you need to give that pedantry award back. :P
I read it as “required beyond constant attention, literally like 30hr [of attention] per day”, not “required attention beyond constantly, literally for like 30hr per day.” ¯\_(ツ)_/¯
No. Because why the child can only get attention for 24 hours per day, other tasks primarily focused on the child (buying nappies, cooking baby-friendly meals, washing bottles, etc.) are what Parent #2 is doing while Parent #1 looks after child.
Not a fan of pedantry. Would like to see less of it in the world.
