General information

As the days go by, the baby starts looking more and more like a real human. Although he or she looks like he or she is always resting because the eyelids are closed (they are fused together), you can be sure that all the other body parts are moving. However, you will be able to feel this only later.

The baby development during the 13th week of pregnancy also includes that the baby is already able to suck his or her thumb. At this point, the little one has about the size of an egg. Now he or she is about three inches long and he or she is constantly gaining weight.

The baby gets stronger

Until now the baby had cartilage instead of bones, but the 13th pregnancy week baby development also includes that the cartilage is slowly being replaced by bones. This is also the time when the ribs appear to protect the inner organs of the little one. The face is more and more defined around the chin and the nose areas.

It’s all about movement

As it has been mentioned before regarding the development of baby at 13 weeks pregnant, you can’t feel the baby move yet, but the specialists can already measure the movements. One of the cutest things that the baby does at this stage is opening and closing his or her tiny mouth.
