How your baby is growing this week

About the size of a bowling pin — roughly 15.7 inches, 3 lbs. Brain is wrinkling into the folds and grooves that store memory. Bone marrow now runs red blood cell production. Eyelids open and close, and the eyes can track a bright light through the belly wall.

What your partner is going through

Heartburn is severe — the uterus crowds the stomach and pushes acid up. Sleep now takes a fortress of pillows: one under the belly, one between the knees, one behind the back. Shortness of breath as the uterus presses the diaphragm. Feet and ankles swell by evening.
