One of my babies is now an insurance clerk so this idea is too late for me. Nonetheless I used to wear babies a lot and they tended to get very heavy. This was a very good thing because it helped me keep in shape for a long time after they were born. But I only carried them on my back and front. Other body parts are available.
The idea is therefore this: stockings into which babies can be inserted, next to the parent's calves or thighs. Give 'em all breathing tubes and with quadruplets you could be carrying eight kilos or more per leg and it would be amazingly strenuous. If they need attention, just roll them down and access the infants for feeding or changing.
And you could fit two more babies on your torso and maybe a couple on your arms and you'd be up to twenty-four kilos. It'd be amazing!-- nineteenthly, Dec 21 2018 //One of my babies is now an insurance clerk// I'm so sorry, [19thly].-- MaxwellBuchanan, Dec 21 2018 Actually we're astonished that she was able to be so "normal".
