Metric system

The baby weighs approx 1 metric ton (1000 kg, the mass of 1 cubic meter of pure water at sea level), up from approx 3.4 kg. She excretes approx 100 liters of pee and poop a day. She eats about 1 microgram of solid food a day. She burns about 1,000,000 kiloJoules of energy per day, dragging herself around on her belly.

The rest is breast milk.

So why am I not losing weight?

I did this in metric, because it's more scientific and precise. At least that's what DH tells me, but that's because he's French and grew up with metric...
