This is what the twins look like at 20 weeks...real little babies...so amazing.
How your babies are growing:
Your babies weigh about 300g now. They are also around 16.5cm long from head to bottom and about 25cm from head to heel. (For the first 20 weeks, when a baby's legs are curled up against his torso and hard to measure, measurements are taken from the top of his head to his bottom — the "crown to rump" measurement. After 20 weeks, he's measured from head to toe.)
They are swallowing more these days, which is good practice for their digestive system. They are also producing meconium, a black, sticky by-product of digestion. This gooey substance will accumulate in their bowels, and you'll see it in their first soiled diapers.
