This is how big Chicklet is this week. Amazingly, for something so tiny (about 1/4 inch long) -there is already a beating heart, leg and arm buds, tissue that will form the lungs, and the eyes and nostrils are beginning to form. In addition, the muscles and bones are forming as well as the pituitary gland, intestines, and ears. I am utterly amazed at how something so small can be developing so rapidly. It truly is the miracle of life.
