Six weeks update

This week's major developments: The nose, mouth, and ears that we will spend so much time kissing in eight months are beginning to take shape. His/her emerging ears are marked by small depressions on the sides of the head, and his/her arms and legs by protruding buds. His/her heart is beating about 100 to 160 times a minute — almost twice as fast as mine — and blood is beginning to course through his/her body. His intestines are developing, and the bud of tissue that will give rise to his/her lungs has appeared. His pituitary gland is forming, as are the rest of his/her brain, muscles, and bones. Right now, Baby T is a quarter of an inch long, about the size of a lentil bean.
