All of his internal organs formed during the first trimester and they will continue to mature during the second and third trimesters to get him ready for life outside of your womb. Although his eyelids are closed he is aware of the bright light outside of your belly. The tiny bones Inside his ears are now working and he can begin to hear some sounds. Talk to him and read to him so that he can get to know the sound of your voice. Because your baby's brain now controls all the muscles in his body, he is able to move. Yes, he can even do somersaults. From his early as the beginning of the second trimester, he could make faces that you'll get to see soon. His arms are now long enough for his hands to touch in front of his stomach. He can also reach his head which he might be scratching with tiny fingernails. By week 16, your baby is 5 inches long and weighs 3 ounces. Until now, she didn't have much control over her movements but now she can make a fist and suck her thumb. You probably can't feel any of the movement yet but just wait, in a few weeks it'll all be different. A white creamy substance called vernix is covering her skin and protecting her while she sits in amniotic fluid for 9 months. Imagine how wrinkly and irritated you skin would be if you sat in a warm bath all day. Your baby has reached the size of a beanie baby this week. Until this point, he's been all skin, bones and hair as fats starts to accumulate on his body. The fine hair will disappear and the skin won't look so translucent. He has hiccuped before but this is the first time you might feel it.
