16 Weeks = Avocado Baby

This morning I weighed myself and I'm still 2.5 pounds down from my pre-pregnancy weight. At my last check in I was the same weight and they were happy with it. So I'm going to assume it is fine until a doctor tells me to worry. I know the baby is taking whatever he needs to grow and be healthy. I'm struggling with some tiredness and I am assuming that is related to my inability to put on any weight. I have had a head cold for most of the week but I seem to be almost over that now. My morning sickness is reduced to puking a few mornings a week. The food aversions are mostly gone which is good news. My most frequent craving has been for shepherd's pie. I'm happy it is for something I actually like and know how to make!

And here's the 16 week update from the web:

How your baby's growing:At 4 1/2 inches long (head to bottom) and 3 1/2 ounces, your baby is about the size of an avocado. In the next three weeks, she'll go through a tremendous growth spurt, though, doubling her weight and adding inches to her length. Her lower limbs are much more developed now. Her head is more erect than it has been, and her eyes have moved toward the front of her head. Your baby's ears are close to their final position, too. Some of her more advanced body systems are working, including her circulatory system and urinary tract. Her heart is now pumping about 25 quarts of blood each day, circulating her total blood volume through her body many times. (By the end of your pregnancy, this will increase to about 190 quarts.) The patterning of her scalp has begun, though her hair isn't recognizable yet. Although closed, her eyes are moving (slowly), and she's even started growing toenails.

Over the past three weeks your astounding growing baby has managed to stretch yet another 2 full inches (totaling about 4.5 inches) and weighs around 3.5 ounces. Yessireee, that’s some pretty serious growth... and with it comes several physical developments! For starters, their head to body ratio is finally starting to even out a bit as the rest of the body is actually growing faster than the head at this point. Yes, your little light bulb is not so top-heavy. Their adorable little limbs have lengthened, almost reaching their normal proportions which they will have at birth. Their eyes are still closed but moving and if you had an ultrasound, which many doctors recommend you have at about this time, you may even see your little one sucking on a thumb, not to mention the necessary signifiers to let you know whether you’ve got a wee lad or lassie.

Your Baby
By pregnancy week 16 your baby is more than 4.5 inches long and may weigh almost 3 ounces.
Changes In Your Growing Baby
Your baby is planning on a huge growth spurt in the upcoming weeks. During pregnancy week 16 your baby has grown strong enough to hold his head straighter. Your baby's eyes and ears are moving into their final position and your baby is focusing much of her energy on her circulation system. By week 16 pregnancy your baby's heart is pumping roughly 25 quarts of blood each day!
During pregnancy at 16 weeks your baby starts growing fine hair on the tope of his head, though some babies will be born very bald despite their best efforts. The color of your baby's hair and even your baby's eyes may change shortly after birth. Many babies are born with blonde hair for example that falls out and turns brown a short time after birth. Still others are born with brown eyes that turn blue within a month or two after birth! Your baby will continue to amaze you in the weeks following pregnancy.
