Your child's body is working hard and growing quickly! Now that the liver and spleen have finished manufacturing blood cells, the bone marrow steps in to assist. This is a significant milestone because it signifies that your baby's body is becoming more independent and able to care for itself. It's astounding to consider all the miraculous processes occurring inside your womb to develop this new life!

Baby's Drinking

Your little one is growing up so fast! Did you know that your baby has now started to take in small amounts of amniotic fluid? While the placenta is still the main source of nourishment, this is an exciting milestone that shows their digestive system is developing and getting ready for the outside world. It won't be long now until they're enjoying all sorts of delicious treats!


21 Week Old Taste Buds Development

Exciting news! Your little one's taste buds are starting to develop and this week, there's a high chance they will taste whatever you eat! That's right, your baby is practicing swallowing and digesting by consuming small amounts of amniotic fluid every day. And here's the best part - the flavor of the amniotic fluid changes based on what you eat! From spicy enchiladas to sweet bananas, your baby is already experiencing a wide variety of tastes. In fact, research has shown that babies who were exposed to different flavors in utero are more likely to enjoy those same flavors after birth. So go ahead and indulge in those veggies because your baby might just follow in your footsteps!

Symptoms During 21 Week Pregnancy

First off, let's tackle the rollercoaster that is your sex drive. As you voyage on this extraordinary journey of life creation, your body's transforming, and with it, so are your sexual desires. The ebb and flow of your libido could see some ups and downs, mimicking the grandest of ocean waves. You might experience a surge of desire, or you may feel it waning. The key here is to remember - there's no 'one-size-fits-all' approach. Your feelings are as unique as your journey. If your libido decides to take a scenic route, dipping in the first trimester, peaking in the second, and then taking a leisurely stroll in the third, that's perfectly fine. Engaging in sexual activity during pregnancy is safe and sound, unless advised otherwise by your doctor or midwife.

Next up, the thundercloud of migraines. While mild headaches might be an unwelcome companion due to hormonal changes or dehydration, it's crucial to be on the lookout for the stormy signs of preeclampsia. If you're hit by a pounding headache, your vision starts playing tricks like blurring or flashing lights, or you experience a nagging soreness below the ribcage, ring up your midwife or maternity unit immediately. Swelling resembling a sudden tide rising in the face, hands, feet, and ankles, coupled with vomiting, can also be a telltale sign.


Lastly, let's shed some light on your crowning glory - your hair. You might notice your hair becoming a lustrous mane during pregnancy, thanks to hormonal changes leading to a slowdown in hair loss. However, post-birth, you might see some strands bidding you farewell. Fear not, this is perfectly normal and just a temporary parting. Most women find their hair makes a glorious comeback over time, with hair loss rarely lasting beyond 15 months post-birth, according to research. So, chin up, mama - your hair will reclaim its voluminous vibrancy in no time at all!

Food to Consume to Alleviate Anemia

Want to boost your iron levels during pregnancy? There are several tasty and nutritious food alternatives that might help treat anemia.

As you are aware, anemia is a common blood illness that may affect both your health and that of your child. With a balanced and healthy diet, however, you can avoid or easily control its symptoms.

Whole grains such as brown rice, fresh leafy greens such as spinach and broccoli, and well cooked red meat are some of the greatest iron-rich foods to integrate into your diet. No worries if you're a vegan or vegetarian! As long as you ingest items from all dietary groups, including iron- and vitamin B12-rich alternatives like meat and fish, you may still maintain a balanced and nutritious diet. See your physician or midwife and begin consuming these delicious meals for a healthy and successful pregnancy!

Bonding With Your Baby

You are halfway through the process of becoming a parent; congrats! Did you realize that your young child can now hear your voice? Indeed, it is time to begin chatting or singing to your infant. This will assist them in recognizing your voice and increase their sense of connection with you. Furthermore, remember to encourage your companion to participate in the fun!

But guess what? You're not alone! Nearly all expectant parents experience anxiety and fear as they embark on this journey. It's a wild ride with twists and turns, but trust us, it's worth it.
