Fetal development from 1 week to 40 weeks in mother womb || pregnancy week by week

Thanks! Share it with your friends!


After fertilization and implantation, a baby is at first just an embryo: two layers of cells from which all the organs and body parts will develop. Growing quickly, your baby is soon about the size of a kidney bean and constantly moving. The heart is beating quickly and the intestines are forming. Your budding son or daughter’s earlobes, eyelids, mouth, and nose are also taking shape.
At the beginning of the second trimester, babies are about 3 1/2 inches long and weigh about 1 1/2 ounces. Tiny, unique fingerprints are now in place, and the heart pumps 25 quarts of blood a day. As the weeks go by, your baby’s skeleton starts to harden from rubbery cartilage to bone, and he or she develops the ability to hear. You’re likely to feel kicks and flutters soon if you haven’t already.
Babies weigh about 2 1/4 pounds by the start of the third trimester. They can blink their eyes, which now sport lashes. And their wrinkled skin is starting to smooth out as they put on baby fat. They’re also developing fingernails, toenails, and real hair (or at least some peach fuzz), and adding billions of neurons to their brain. Your blossoming baby will spend his or her final weeks in utero putting on weight. At full term, the average baby is more than 19 inches long and weighs nearly 7 pounds.
Every week brings new developments when you’re expecting. Your baby’s changing day by day, and your body is keeping pace with developments of its own. Find out what’s going on, inside and out, with this week-by-week pregnancy calendar guide.
