Finding a rhythm 💛

Just past the halfway mark, your little one is settling into a daily rhythm of sleeping, waking and wriggling. You may be starting to notice a pattern too.

📌 Week 21 at a glance

• Trimester: Second
• Baby's size: about the size of a carrot (around 26.7 cm head to heel)
• Still to come: roughly 19 weeks (a typical pregnancy lasts around 40 weeks)

🌱 Your little one this week

At 21 weeks, your baby weighs around 360 g and measures about 26.7 cm from head to heel, roughly the size of a carrot. Your baby is now heavier than the placenta, which keeps growing to provide food and carry away waste.

A fine, downy layer of hair called lanugo has been growing, probably to help keep your baby at just the right temperature, and it usually disappears before birth. Hair and eyebrows are developing too. Your baby can now hear noises and voices outside the womb, so if you sing to your bump, however it sounds, you'll have a very loyal fan.

Your baby is moving around a lot and settling into patterns of waking and sleeping. The digestive system is practising too, as your baby swallows small amounts of amniotic fluid. You may feel movements as kicks, rolls or gentle taps.

🌷 And how about you, Mum?

Many mums feel the baby move more clearly around now. If you haven't yet, that's still within the range of normal, especially in a first pregnancy. Your baby may be wide awake just when you're ready to sleep, so napping when you can helps make up for lost rest.

You may feel a little unsteady as your bump grows, because your centre of gravity has changed and your joints are looser. If you have a tumble, try not to panic, as your baby is well protected, but let your doctor or midwife know as soon as you can. You may also notice swollen feet or ankles by the end of the day, a bigger appetite, or an itchy tummy as the skin stretches. These are common in the second trimester.

🍽️ Food for thought: vitamin B6

Vitamin B6 helps the body use protein and energy from food, and contributes to normal functioning of the nervous system. It's found in a wide range of everyday foods.

Foods that contain vitamin B6 include:

• Chicken and fish
• Bananas
• Potatoes and sweet potato (keledek)
• Chickpeas and other beans
• Wholegrains and fortified cereals

If you'd like personal advice about food or supplements, your doctor, midwife or dietitian is happy to help.

✨ Little things that may feel nice

• Many mums find that putting their feet up in the evening helps with swollen feet
• Comfortable, supportive shoes can feel kind as your body changes
• Moisturiser can feel soothing on a stretching tummy
• A few quiet minutes to notice your baby's movements can be a lovely daily habit

🩺 Coming up

If you haven't had your detailed mid-pregnancy scan yet, it's usually offered at around 18 to 20 weeks. Routine antenatal visits continue, and your doctor or midwife can tell you what's planned at your clinic. In Malaysia, this can be at a Klinik Kesihatan or a private clinic of your choice.

If anything unexpected came up at your scan, it's natural to feel worried. Please talk through your options with your doctor or midwife. You don't have to go through it alone.

👨‍👩‍👧 Partner's corner

Baby's movements may soon be strong enough to feel from the outside. Resting a hand on the bump together, quietly, can be a sweet shared moment. It may take a little patience, and that's fine.

❓ Quick questions

Why are my feet a bit swollen?
Mild swelling is common in pregnancy as the body holds more fluid. Putting your feet up often helps. If swelling is sudden or severe, or comes with other symptoms, please speak to your doctor or midwife.

Can others feel the baby kick yet?
Sometimes, from around now or a little later. It varies from mum to mum.

💛 A little moment for the two of you

Twenty-one weeks. Your baby is finding a rhythm, and you're finding yours too.

Little rhythms, big love. 🦕
