The sixth month marks the end of the 2nd trimester of pregnancy. During this time, significant changes for both mother and baby will once again occur. At the sixth month of pregnancy, the sizes of both mother and child will have increased particularly if the mother is not on a controlled diet.
How Big is a 6-Month Fetus?
On the average, the fetus will be about 11.8 inches long and will weigh approximately 590 grams or 20.8 ounces. If on the fifth month, the fetus appears to still be thin even if he looks more fully developed; by the sixth month, the fetus will now have gained a small amount of baby fat.
As the sixth month progresses, the fetus should begin to grow both in length and weight so much so that by the end of the sixth month, the baby’s average length will now be around 13.5 inches and his weight will be about 907 grams or 32 ounces.
For a more visual representation of the fetus’ size, by this time he will be about the size of the average eggplant.
The baby’s development by the sixth month is quite remarkable, in that he will now begin to respond to light, where if you direct light to the belly; the baby’s head will turn towards the light source.
He will also begin to respond to touch. As parents rub the belly and make soft cooing sounds, the baby will react to these loving gestures. Around this time, the baby’s eyelids will begin to open and close, mostly as a reaction to light and when sleeping or waking-up.
He begins to take small breaths, practicing the lungs for when he gets out of the womb at birth. This stage is very important as well to the baby’s immune system as this is the phase where he begins to draw-up the mother’s antibodies also in preparation for its life after birth.
The belly will now also have increased in size as the baby gets bigger and begins to gain baby fat. One of the more noticeable changes is the decrease in the mother’s need to visit the bathroom to urinate.
As the mother’s energy level begins to get more and more to its normal level, she will have begun “nesting.” This means that she will be more focused on preparing the baby’s room, cleaning the entire house and getting all the things the baby will need to start life outside the womb.
By this time, mothers may begin to leak in the breasts, may start to develop hemorrhoids and bleeding gums and nosebleed may still continue. Sexually, the mother’s libido could be at an all-time high at this point.
