Week 4 {Development}



Update: Mommy has taken several pregnancy tests, each with a different answer than the one before! It looks like Baby Suarez isn’t quite ready to make an announcement. If she is, she’s making incredible strides this week.

This week marks the beginning of the embryonic period. From now until 10 weeks, all of Baby Suarez’s organs will begin to develop and some will even begin to function. As a result, this is the time when she'll be most vulnerable to anything that might interfere with her development.

Right now your baby is an embryo the size of a poppy seed, consisting of two layers: the epiblast and the hypoblast, from which all of her organs and body parts will develop.

The primitive placenta is also made up of two layers at this point. Its cells are tunneling into the lining of Mommy’s uterus, creating spaces for your blood to flow so that the developed placenta will be able to provide nutrients and oxygen to growing Baby Suarez when it starts to function at the end of this week.

Also present now are the amniotic sac, which will house Baby Suarez; the amniotic fluid, which will cushion her as she grows; and the yolk sac, which produces the red blood cells and helps deliver nutrients to her until the placenta has developed and is ready to take over this duty.
