IMO, all stages are critical. There is always something happening to the baby inside the womb whatever age the baby is or whatever trimester the mother is in.

Prenatal care is important. this is why women should get the proper attention and care during pregnancy. this is a must for the mother and the baby as well.

Hey there!

Yes the first trimester is one of the most crucial stages of pregnancy. This is where organs begin to develop. This is a sensitive time for both mother and child.

The first trimester is critical indeed. But after this, developed organs continue to mature. During the second trimester, your baby will learn things it needs to surive outside the womb.

By the sixth month, when the fetus has grown to 36mm long and 30-690 grams in weight, the skeleton and tiny fine hairs begin to form. Eyelids and eyelashes also start to form. The baby's skin is red and wrinkled. This is in the 2nd trimester.

the 1st trimester comprises the 1st three months of conception. During the 1st few weeks of development, the embryo is observed as a small disk with a groove forming down the middle. the spinal cord and the brain also start to develop. its bending position toward the tail is visible. by the end of the first month, the embryo is about 5 mm. long, and the tail, gills, notochord and segments in the embryo's body begin to develop.

I agree with this because it is the time when the embryo's the head grow and the time when the mother should not take any medication unless it is prescribed by the physician. Take extra careful Moms!
