Your baby measures about 3.7 to 4.1 inches (about 9.3 to 10.3cm) from crown to rump and weighs about 1.75 ounces (50g).
Your baby's bones still consist of soft cartilage but they are now beginning to harden and the development of the bones and the marrow continues. Her ears are developing into a more recognizable shape and any hair already on the head and brows will become thicker.
Your baby may already be sucking her thumb.
Her skin is thin and translucent and all her blood vessels can be seen through it.
Her hair continues to grow on her head and her eyebrows. If her hair will be dark, the follicles will start to generate pigment to color her hair.
Your baby is moving more now and is becoming increasingly flexible. She can bend her arms at the elbows and wrists and she can make tiny fists with her hands.
