In the 23rd week, we went to have regular check.  This time, we finally see Chester's face (his 4-D photo).  First of all, I must record down that Chester had grown up a lot in the last month and I have therefore gained 10 lbs just in 1 single month (well, I would say it was because of Chester's growth although there was no prove if the weight actually contribute to I myself rather then him =p).  My tummy grows significantly bigger.  Chester is now in 2lb already while when I look at the info below that baby in the same week should only be 1.1 lb..no wonder why the doctor worry.  Everyone thinks that I am gonna deliver soon.  Don’t know why, it is the same as when I had Jacob, my tummy is much bigger than others.  May be it is because I carry two big babies?  So far, Jacob’s height is always above 97percentile.  

According to Dr. Wan, Chester will be definitely big (he didn’t say this about Jacob at that time but he seems to be so sure about Chester..but it turns out that Jacob is already quite tall..so, I can’t imagine how big Chester will be).  Talking back about the 4-D photos, as the Doctor said Chester has a nice nose.  From the 4-D picture, it seems that Chester has Leonard’s nose.  Later, when I compare Chester’s photo with Jacob’s first 4-D photos, I would say that they really have very different nose.  Jacob definitely have mine nose while Chester’s one is more like Daddy.  After all, the most important thing is that Dr. Wan said the baby looks healthy.  Everything is fine except that Mummy has to cut sweet things including fruit =p  Well, I will try my best ~.*  Otherwise, I will have hard time in delivering Chester!  

Besides, I started feeling Chester’s movement since week 15-17.  He moves occasionally, a bit active but not very.  I think that Chester is a happy, funny, a bit active but very gentle little boy. 

Week Twenty-One

• White blood cells are under production. Leukocytes (or white blood cells) form our body's defense sytems. They help fight infections and diseases.
• Your little one's skin has changed from translucent to become more opaque.
• Your infant's tongue is fully formed. If you were able to peek you might catch your son or daughter practicing giving you a raspberry!
• If your baby is a girl, her womb and vagina are formed. Unlike males, females have a limited supply of eggs in their lifetime. At this point your daughter will have 6 million eggs. This amount decreases to approximately one million by birth.
• Baby swallows more this week. After your baby takes in amniotic fluid, his body absorbs the water in the liquid and moves the rest into the large bowel. This is good practice for his digestive system!
• Wake and sleep periods become more consistent. Some research suggests that baby sets her internal clock to match the outside world's even before birth! Your eating and sleeping habits as well levels of light and noise serve as her signals.
• Length is now measured crown to heel.
• Baby measures about 10.51 inches (26.7cm) and weighs nearly 12.7 ounces (360g).

Week Twenty-Two

• Your baby weighs close to a pound at this point!
• Your baby can now hear your conversations more clearly than before!. When you talk, read, or sing, expect her to hear you. Studies have found that newborns will suck more vigorously when read to from a book they heard frequently in utero.
• Eyelids and eyebrows are fully formed.
• Fingernails have grown to the end of the fingers.
• Be prepared for all those "Why" questions coming! Your baby's brain has entered a stage of rapid growth, especially in what's called the germinal matrix. This structure deep in the middle of the brain serves as a kind of factory for brain cells and disappears shortly before birth. But the brain's amazing expansion program continues until around the five birthday.
• With some help from mom, baby's liver is starting to break down bilirubin, a substance produced by red blood cells.
• If your baby is male his testes begin their descent to the scrotum.
• Primitive sperm have formed and he is producing testosterone.
• Length is 10.94 inches (27.8cm); weight is nearly 1 pound (430gm).

Week Twenty-Three

• Proportions of the body are now quite similar to a newborn although thinner since he hasn't begun to form body fat.
• Bones located in the middle ear harden.
• Your baby is able to hear. (Dads, did you know: low-frequency sounds mimicking a male voice penetrate the abdomen and uterine wall better than the higher frequencies of the female voice?)
• The eyes are formed, though the iris still lacks pigmentation.
• The pancreas, essential in the production of hormones, is developing steadily. She has begun producing insulin, important for the breakdown of sugars.
• If born now, your baby has a 15% chance of survival, his odds going up with each passing day. .
• The average baby at this stage weighs 1.1 pound (501gm) and is 11.38 inches (28.9cm) long.

• Bring on the bulk! Baby gains about 6 ounces this week. The weight is in muscle, bone mass and organs.
• His body begins to fill out with his appearance increasingly becoming more like a newborn.
• Taste buds begin to form. If mom drinks something strange or bitter, baby may be observed showing his distaste.
• Little creases have appeared on his palms. The muscular coordination of his hands has improved as he sucks his thumb.
• Over the next seven days the sweat glands will be forming in the skin.
• His lungs are developing "branches" of the respiratory "tree" and cells that produce surfactant, a substance that helps the air sacs inflate easily.
• This week your baby is officially considered viable.
• Baby weighs 1.3 pound (600gm) and is 11.8 inches (30cm) long -- almost the length of a ruler!
