Pregnancy 10 weeks-baby development

By 10 weeks, the fetus is already a recognizable human being. During the next few weeks the fetus will grow rapidly and steadily, at a rate of 1/2 in per week and its weight will increase five-fold.

The fingers and toes are separating into individual digits and tiny nails. The muscles of the chest wall are starting to develop and practice breathing movements along with the occasional hiccups and swallowing movements can be seen on the ultrasound.

Your baby is starting to make reflex responses to external stimuli. For example, if your abdomen is prodded, the baby will try to wriggle away from the intruding finger. If a hand or foot happens to brush against the baby's mouth, the lips purse and the forehead may wrinkle-this is the very first sign of the future sucking reflex.

The ovaries and testes have fully formed, and the external genitalia are developing from a small swelling between the fetal legs into a recognizable penis or clitoris. In theory, an experienced ultrasound scanner may to be able to determine the sex of your child at this early stage, but if you rely on the diagnosis now you may might be in for a surprise at the birth.

The heart is now fully functional and pumping blood to all parts of the fetal body at a rate of 110-160 beats per minute. It may be possible to hear the heartbeat with a sonicaid machine placed over your lower abdomen, just above the pubic bone. This device uses Doppler ultrasound waves and is completely harmless to your baby.

The fetal stomach i snow linked to the mouth and the intestines- an important development because the fetus now begins to swallow small amounts of amniotic fluid. This will later be excreted as urine when the fetal kidneys start to function.
