16 weeks

-The little baby is 15 centimeters long today! Just to give you an idea of how big this is, it's about the length of my hand.
-Today's ultrasound showed that the baby's heartbeat is about 153. The doc said that it looks like we have a healthy baby!
-His/her heart is pumping 25 quarts of blood a day!
-The patterning of the baby's scalp is beginning.
-He/she is getting more playful and may have discovered his/her first toy: the umbilical cord.
-Over the next few weeks, the baby is going to have a big growth spurt!
