More about conditions that develop during pregnancy. More about how your baby lies in the womb. You may be asked to think about having a planned caesarean section to prevent issues for you and your babies. This is more likely if one or both twins is in a position that would make a vaginal birth difficult.

More about having a caesarean section. Though you probably can't feel it yet, your twins are busy kicking and stretching. Their hands can make fists; their fingers are developing ridges that will become permanent, unique prints; and their tiny fingernails are starting to grow in.

Their faces are beginning to take shape — with noses, eyes, and upper lips developing as tissue starts to harden into bone.

Closed eyelids cover their eyes, and tooth buds have already sprouted and put down roots in their gums. Their heads are large, accounting for about half of their size! Fine hair called lanugo is developing on the twins' heads, and their skin is almost transparent.

They can grimace and make sucking motions. Their hearts are pumping blood, and they have started peeing out the amniotic fluid they've been swallowing. You can see their sex organs during an ultrasound.

Talk to your twins — their ears are protruding, and they may be able to hear you now! Lanugo now covers their body. To protect their skin from its immersion in amniotic fluid, it's developing a greasy white coating called vernix. Eyebrows and eyelashes are formed, and your babies can accidentally scratch themselves with their fingernails now. Meconium — made up of digestive secretions, sloughed cells, and swallowed amniotic fluid — is collecting in their bowels and will be their first bowel movement after birth.

Things are starting to get a little crowded for them now as they grow bigger. And you may notice them becoming more active now. Your mid-pregnancy ultrasound between 18 and 22 weeks will identify the sex of your babies, if you like. The sizes of the babies and their heartbeats will be measured, along with the amount of amniotic fluid.

Your babies' skin is red and wrinkled now, no matter what color it will be after birth, and their eyebrows are growing in. They begin to store fat, and their lower airways are developing. They're growing more hair on their heads and taste buds on their tongues. Their bone marrow has started making blood cells. Testicles will descend into the scrotum of boy babies, and eggs are filling the ovaries of girl babies.

The lungs aren't working fully, but they're formed and developing. The babies may even respond to sounds — such as music or your voice — by moving. Your twins' brains are growing rapidly. Though they're sleeping most of the time with eyelids closed , they can open their eyelids, which now sport eyelashes. They may even turn toward a light. Layers of fat are building up under their skin, smoothing it out. If both babies are lying horizontally, you'll almost definitely have a C-section.
