At 16 weeks pregnant, you're halfway through your second trimester. This period is crucial for your foetus's growth and development. During this time, you'll experience various physical and emotional changes. Understanding these changes can help you navigate this phase of your pregnancy more smoothly.
Foetal Development at 16 Weeks
At 16 weeks pregnant, your foetus measures approximately 4.3 inches (10.9 cm) in length and weighs around 2.9 ounces (82 grams). Several significant developments are occurring:

- Fat layers are forming under the skin, helping to regulate the foetus's body temperature.
- The digestive system is practicing contractions, preparing for life outside the womb.
- The pancreas starts producing digestive enzymes.
- The foetus's kidneys are functioning and producing urine.
Sensory Development
The foetus's senses are also maturing:
- The eyes are formed, and although the eyelids are fused shut, the foetus can detect light.
- The ears are developed, and the foetus can detect sounds outside the womb.
- The nose and mouth are developed, and the foetus is practicing breathing and swallowing.
- The skin is sensitive to touch.
