The Fetal Development At 12 Weeks
By 12 weeks, your baby’s organs and body systems are starting to function. The most exciting development is that your baby’s nervous system is now connected to their muscles, which means that they can move their limbs and even suck their thumb! Other significant milestones include:
The digestive system is starting to work, and your baby can swallow amniotic fluid
The kidneys are producing urine, which they will continue to do throughout the rest of the pregnancy
The liver is producing bile, which aids in digestion
The bone marrow is making white blood cells, which are crucial for fighting infections
The vocal cords are forming, and your baby can make sounds (although you won’t be able to hear them yet!)
The Physical Changes In Your Baby
At 12 weeks, your baby is around 2.5 inches long, and their body is starting to look more human-like. Their head is still large in proportion to their body, but their face is taking shape. Their eyes have moved closer together, and their ears are in their correct positions. Their fingers and toes have separated, and their nails are starting to grow. Your baby’s skin is still transparent, but it’s becoming less so.
Around 12 weeks, you’ll have your first ultrasound scan. This scan is usually done transvaginally, which means that a small probe is inserted into your vagina to get a better view of your baby. During the scan, the sonographer will measure your baby’s crown-rump length, which is the distance from the top of their head to their bottom. This measurement can give an accurate estimate of your due date. The sonographer will also check for any visible abnormalities and make sure that your baby’s organs are developing correctly.
What Can You Do To Support Your Baby’s Development?
The good news is that at 12 weeks, your baby is pretty self-sufficient. However, there are a few things you can do to support their development:
Eat a healthy diet that includes plenty of fruits, vegetables, lean protein, and whole grains
Take prenatal vitamins that contain folic acid, iron, and other essential nutrients
Avoid alcohol, smoking, and drugs that can harm your baby’s development
Stay active by doing low-impact exercises like walking, swimming, or yoga
Reduce stress by getting enough sleep, practicing relaxation techniques, and seeking support from loved ones
At 12 weeks, your baby has come a long way and is starting to look more like a little human. Their organs and systems are functioning, and they can even move their limbs and make sounds. Your 12-week scan is an exciting milestone that will give you a glimpse of your baby’s development and help you estimate your due date. By taking care of yourself and avoiding harmful substances, you can support your baby’s growth and development in the coming weeks and months.
