As you approach the midpoint of your pregnancy journey, week 21 brings a flurry of developmental milestones for your growing baby. At this stage, your little one is about the size of a small cantaloupe, measuring approximately 10.5 inches in length and weighing around 12.7 ounces. This period is crucial for sensory development, motor skills enhancement, and overall growth.
Fetal Development at Week 21
During week 21, your baby's senses are becoming increasingly refined. The eyes, which have been forming since earlier weeks, start to develop further, with the retina beginning to form. Although the eyelids are fused shut to protect the developing eyes, your baby can detect light and darkness. The skin starts to thicken, and fat layers form, which will help regulate body temperature after birth.
Sensory and Motor Skills Development
Your baby's sensory and motor skills are rapidly advancing. The skin is sensitive to touch, and your baby might even be able to detect movement and changes in pressure. Taste buds are forming on the tongue, and your baby can differentiate between sweet and sour tastes. Motor skills are also improving; your baby can swallow, kick, and even suck its thumb. These actions are crucial for feeding and self-soothing behaviors post-birth.
| Developmental Milestone | Description |

| Eyelid Development | Eyelids are fused shut but developing to protect the eyes. |
| Skin Sensitivity | Skin is sensitive to touch and can detect movement. |

Maternal Changes and Health Tips
As your baby grows, you might experience various physical changes and discomforts. Back pain, due to the expanding uterus and shifting posture, is common. Engaging in prenatal exercises, like yoga or swimming, can help alleviate these symptoms. Additionally, you might notice changes in your skin, such as a darkening of the skin around your nipples (areola) and a line running from your navel to your pubic bone (linea nigra).
Nutritional Needs and Lifestyle Adjustments
Maintaining a healthy diet and lifestyle is vital during pregnancy. Increase your intake of protein, iron, and calcium to support your baby's growth and your own health. Staying hydrated and avoiding excessive caffeine and alcohol are also crucial.
