Week 6: Lentil bean baby

The little one is lentil bean size today at 6 weeks! This week's major developments: The nose, mouth, and ears are beginning to take shape. If I could see into my uterus, I'd find an oversize head and dark spots where the baby's eyes and nostrils are starting to form. Her/his little ears are marked by small depressions on the sides of the head, and the baby's arms and legs by protruding buds. The heart is beating about 100 to 160 times a minute — almost twice as fast as mine— and blood is beginning to course through the body. The intestines are developing, and the bud of tissue that will give rise to her/his lungs has appeared. The pituitary gland is forming, as are the rest of his brain, muscles, and bones. How fun!!
