How big are the babies? By 16 weeks, your twins will each grow to 10cm (3.9in), from crown to rump. They now weigh about 100g (0.2lb) each.
Your twins' unique fingerprints are already in place. And when you poke your stomach gently and they feel it, your twins may start rooting and sucking whatever is in front of their mouths. This could be a hand, foot or an umbilical cord. This sucking reflex will give them the training they need for breastfeeding once they're born.
If one or both of your twins are girls, they will now have approximately two million eggs in their ovaries, dropping to a million by the time they're born.
Your twins' bodies are now growing faster than their heads. Their parchment-thin skin covers itself with thick, downy hair (lanugo). Though their eyebrows are beginning to grow and they're sprouting hair on top of their heads, this may change in texture and colour once they're born.
Your babies' legs are growing longer than their arms, each fingernail is fully formed, and all their joints and limbs can move. Their external genitals may be developed enough for a sonographer to tell whether you're expecting boys or girls. You may be able to find out the sex of your babies by ultrasound at this stage.
Your twins' skeletons are mostly rubbery cartilage, which will later harden. A protective substance (myelin) slowly begins to wrap around the spinal cord.
Your twins' chests move up and down to mimic breathing, but rather than air, they're taking in amniotic fluid, which helps their lungs to develop. Your twins are also starting to have hiccups. Hiccups are an essential reflex which trains their diaphragms, the muscles they need for breathing as soon as they are born.
Weight gain/loss: In the first trimester, I lost 7 lbs but I have gained back 2.5 of that 7 :) I don't think it will be too much longer and I will be piling on the weight
Maternity clothes: Yup, all maternity clothes now :)
Stretch marks: NOPE! :) I coat myself in bio oil and have been able to prevent them so far! I DO have that dark line beginning to form from my boobs to my pelvic bone! Linea Nigra I believe it is called!
Best moment of the week: Any time I feel my babies, it is the best time :)
Movement: LOTS! Mainly in the evenings. I feel a LOT of movement from the little one on my right side and less from baby on the left. When I eat anything cold, they move lots!
Symptoms: Big belly, big boobs :) When I sneeze, I always dribble hahaha
Gender: Not sure! I am still thinking two boys!
Anything making you sick or queasy? Well, nothing specific really. I have been feeling much better. I have had a few evenings throwing up but really nothing in particular set me off. I have to eat when I am hungry or I will be very nauseated.
Labor signs? Nope and they can stay far, far away!
Wedding rings on/off? On
Mood? BEST mood :)
Looking forward to? This afternoon's ultrasound! Cannot wait to see our little twinkies!
Sleep: Been sleeping much better lately :) REALLY struggling with sleeping on my left side. I always end up on my right!
