By the end of this week your baby will have tripled in size! His heart is now beating with a regular rhythm. It's still too faint to be picked up by your doctor's stethoscope, but if you have an ultrasound at some point over the next few weeks it will probably be visible as a tiny, pulsing dot in the middle of his mini body. Fun fact: From now until birth, your child's heart will beat about 150 times a minute -- twice the average adult rate. Also this week, your baby's brain hemispheres are forming -- and brain waves can now be recorded. 6 of 42
