What is developing at 16 weeks

About the size of an avocado, your baby is growing stronger by the day. The little muscles are developing, the heart is pumping a steady amount of blood, and the eyes will soon begin making small movements behind closed lids. Some people start to feel the first faint flutters of movement around now.

Your body

What you may be feeling

You may feel more like yourself with steadier energy and an easing of early symptoms. A growing belly can bring some backache or round ligament tugging, and you might notice your balance shifting slightly. A few people begin to notice the first faint, bubbly flutters of fetal movement around now, often called quickening, though most do not feel it until 18 to 20 weeks or later.

Tips for week 16

Paying attention to posture and wearing supportive shoes can ease back comfort as your center of gravity changes. If you have not felt movement yet, do not worry, as it varies widely and often becomes clearer in the coming weeks. If you have not felt any movement by 24 weeks, let your provider know. Keep nourishing your body with iron rich foods to support your expanding blood supply.
