zI love watching those modern 4D ultrasounds, they are just so perfect. I have a video of my daughter sucking her thumb when she was a 15 weeks old fetus, can you believe it? Today, she is a 20 months old baby and sucks her thumb just as she did when she was a peanut inside my womb. I also have a video of my son, quite recent, at 18 weeks and he sleeps like an angel, I can see his facial feaures so clearly. The miracle of birth, but also the miracle of modern technology that allows us to have a feeling of what life before birth is like.
