How big is a baby at 10 weeks? During the tenth week of pregnancy, your baby’s the size of a strawberry. Although he/she measures just a little over an inch or so, your baby has completed the most critical portion of the development phase. His/her basic physiology is now in place, so his organs and tissues are now rapidly growing.
Much to your enjoyment, your baby is taking a very human shape right now, with most of his organs fully formed. At this point, his arms are the size of this number 1, so no need to go and buy a baseball bat or Barbie doll yet!
Pregnancy Symptoms at 10 Weeks
What to expect at 10 weeks pregnant? The tenth week of pregnancy is the prime time for an antenatal visit to your ob-gyn. You will probably want an ultrasound to hear your little one’s heartbeat — and be prepared to feel moved by this intense, beautiful sound!
During the tenth week of pregnancy, your baby’s jawbones are starting to form, along with his/her milk teeth (which won’t break through the gums until he/she is around 6 months old). The fingers and toes are no longer webbed — they’re distinctively formed, and your little one can actually move them. He/she can even bend his/her arm at the wrist.
The spinal nerves are beginning to stretch out from the spinal cord, and some fuzzy hair has developed on the skin. Moreover, baby boys are already producing testosterone. The liver has started to make red blood cells, and the yolk sac is now disappearing slowly. Although they continue to develop through pregnancy, most vital organs (the brain, kidneys, intestines etc) are functioning. Tiny nails are now forming on the fingers and toes. Since the brain sits very high in his head, the forehead is temporarily bulging at this point. The outline of the spine is more clearly defined as well. Furthermore, the baby is swallowing a lot of fluid, and making lots of movements inside your womb. The stomach is producing digestive juices, whereas the kidneys (that is, the fourth set of kidneys) are producing more urine.
