Your fetus weighs over 600 grams. He still has little body fat and his skin is fragile. However, he’s now well-proportioned and his brain is growing rapidly. His skin is pinker, and more opaque.
His taste buds are now forming, and, he can start recognizing sweet taste. The inner ear (it controls balance in the body) is now completely developed, and your baby is starting to get a feel of whether he or she is upside-down or right side up inside your amniotic sac.
His hearing is further developing. He can now hear internal body sounds air exhaling from your lungs (deep breath now), but also external sounds such as your voice, your partner’s voice (which your baby will be able to recognize at birth) and even very loud external sounds.
