Week 11

My Baby's Development

From week 11 to 20, your baby will be growing rapidly, increasing in size from about 2 inches (5cm) to about 8 inches (20cm) from crown to rump. To accommodate all this growth, the blood vessels in the placenta are increasing in both size and volume to provide the baby with more nutrients.

Facial development continues as the ears are moving toward their final position on the sides of the head. If you saw a picture of your baby now, you'd think you had a genius on your hands. Your baby's head is about half of the body length!

Although your baby's reproductive organs are developing rapidly, the external genitals of boys and girls appear somewhat similar until the end of this week. It will be clearly differentiated by week 14.

My Body

Nourishing your baby usually requires that you gain weight. In most cases, the recommended weight gain is about 25 to 35 pounds (11.3 to 15.9kg) over your pregnancy. If you were overweight or underweight during your pregnancy, your health care provider may have different recommendations for your weight control.
