This is a baby movement stage.
This is a period of tremendous growth for your baby. Your baby is also growing muscle and is getting stronger every day. As your baby becomes stronger, he will move about more energetically, particularly when you are trying to get some sleep! His teeth are already beginning to form within his jawbone. He may have some hair on his head, including eyebrows and eyelashes. Your baby’s fingernails have grown to the tips of the fingers and he can clench his fists.
The internal organs are maturing. Fat is now being stored beneath your baby’s skin. The blood cells take over for the liver the job of producing blood. Your baby’s gall bladder will become functional, producing bile that is necessary for digestion.
Your baby sleeps and wakes at regular intervals. You will find that your baby is much more active now. He or she turns from side to side and head over heels. Your baby may suck its thumb. Exploring the structures inside your uterus may become baby’s prime entertainment.
Babies are measured from the crown (or top) of the head to the rump (or bottom) until about 20 weeks. After that, they are measured from head to heel.
Baby is now about 7 inches (17 cm) Crown to Rump, about 10 inches (25 cm) from head to heel.
Baby weighs roughly 11 ounces (about 300 grams).
You are getting bigger every day, and during the fifth month you should start to feel your baby’s movements, which begin as light, fluttery sensations. Your skin might darken and stretch marks may appear on your abdomen or breasts. Your breasts may begin to produce colostrum. Your gums might bleed and you may have a congested nose. Vaginal discharge may increase during this time as well .
