Week 6: Sweet Pea (.25 in)

This week's major developments: The nose, mouth, and ears that we'll spend so much time kissing in eight months are beginning to take shape. If you could see Baby Johnson, you'd find an oversize head and dark spots whise his eyes and nostrils are starting to form. His emerging ears are marked by small depressions on the sides of the head, and his arms and legs by protruding buds. His heart is beating about 100 to 160 times a minute — almost twice as fast as ours — and blood is beginning to course through his body. His intestines are developing, and the bud of tissue that will give rise to his lungs has appeared. His pituitary gland is forming, as are the rest of his brain, muscles, and bones. Right now, baby is a quarter of an inch long, about the size of a sweet pea.
