WEEK OF APRIL 22 (Fifth week of development)
By 4 weeks the clear amnion surrounds the #embryo in a fluid-filled sac. This sterile liquid, called amniotic (am-nē-ot'ik) fluid, provides the embryo with protection from injury. If an embryo is not human why is there a natural protection from injury? See more at
With #heartbeatbill being passed in many states think about this fact: The heart beats about 113 times per minute. The heart changes color as blood enters & leaves its chambers with each beat. The heart will beat 54 million times before birth. See more
In the developing embryo rapid brain growth is evidenced by the changing appearance of the forebrain, midbrain, and hindbrain. It doesn’t take a scientist to know if the embryo has a brain it’s more than a blob of tissues. See more at
At 4-5 weeks cerebral hemispheres appear, gradually becoming the largest parts of the brain. Functions controlled by the cerebral hemispheres include thought, learning, memory, speech, vision, hearing, voluntary movement, & problem-solving. See more at
WEEK OF APRIL 15 (Fourth week of development)
Thump-thump, thump-thump—what’s that sound? #BabyChris has a heartbeat! Just three weeks from conception, the embryonic heart is already taking shape. It will beat 54 MILLION times before Chris is born.
It’s week 3 in the life of #BabyChris, and he or she is growing rapidly! His or her body has divided into three layers—ectoderm, mesoderm, and endoderm—which will soon give rise to the major organ systems. Want to know more? Download the See Baby App.
Learning is a lifelong process, and it begins early! Three weeks after conception, #BabyChris has already developed the forebrain, midbrain, and hindbrain structures that will one day allow Chris to learn all about the outside world.
#BabyChris is two weeks old! He or she is producing the pregnancy hormone hCG, which can be detected in the urine via a pregnancy test. Chris’s mom can get a FREE test at her local pregnancy center. She’s about to get huge news!
It’s been two weeks since #BabyChris was conceived. He or she is now fully implanted and the placenta is forming. Chris receives crucial nutrients via a yolk sac. Learn more by downloading the See Baby App!

In one short week, #BabyChris has grown from a single cell to several hundred! Download the See Baby App to follow Baby Chris’s progress.
The life of #BabyChris began one week ago. He or she has traveled from the fallopian tube to the uterus and is now implanting into the endometrium (uterine lining), which will provide critical nutrients throughout pregnancy.
#BabyChris is growing fast! He or she is made up of stem cells, which have the power to produce over 200 cell types. Learn more by downloading the See Baby App.
It's been one week since #BabyChris was conceived. He or she is now in the blastocyst stage and growing increasingly complex. Download the See Baby App to follow Chris’s nine-month journey.

We're going on a nine-month journey! #BabyChris was conceived today. Follow his or her progress by downloading the See Baby app.
Meet #BabyChris! His or her life began today when sperm met egg. Genetic traits from eye color to double-jointedness are already determined. Download the See Baby app to watch Baby Chris grow!
Thousands of unique, unrepeatable babies have been conceived today and are due to be born around Christmas. We’ve named one of them Chris. Follow the #BabyChris hashtag and download the See Baby app to follow his or her journey to birth!
You, me, and every person you've ever met: we all began life as a single cell. #BabyChris is just one cell big today, but will grow very quickly over the next nine months! We’ll tweet Baby Chris’s progress every Monday.
