Your baby is about the size of a peach and is growing rapidly. Crown to rump, your baby measures 2.6 to 3.1 inches (6.5 to 7.8cm) and weighs 0.5 to 0.7 ounces (14 to 20g).

Your baby's legs are longer than her arms and her skin is red and transparent. Her eyelids are fused together and won't open for about four more months. Her arms are long enough to reach her mouth and she may begin to place her thumb in her mouth. Her sucking reflex, however, is not yet developed.

The tissue that will become your baby's bones is being laid out, especially around her head and her arms and legs. Some ribs may be distinguished at this time. The nose and chin are more prominent now.

Your baby will begin to practice breathing in the next few weeks as her chest rises and falls in mock breathing motions. She will also swallow small amounts of amniotic fluid which will be passed as urine.

Your placenta is providing all of your baby's needs for nutrition, oxygen and waste disposal, though the amniotic fluid will become more important later on.

All major components of the body are formed and now must grow and mature. From now on, your baby's development will consist primarily of organ maturity and growth and body refinement.
