Baby development at 23 weeks

What does my baby look like? And, what size is my baby?

In week 23 of pregnancy, your baby will have grown to around 20cm in length and weigh about 450g – roughly the size of a grapefruit1.

Your baby is gaining weight fast now. At this stage, his or her skin will still be transparent and appear as if it’s a little too big. That’s because it grows faster than their body, which then plays catch-up as it expands by storing fat. As your baby stores fat, their skin will lose its delicate, transparent appearance and start looking plumper and more solid.

By now, you should feel your baby moving regularly. Along with kicking, twisting, turning and stretching, your baby can now grasp the umbilical cord if it passes near their hand.

His or her limbs will now be in proportion, and your little one will start to look more like the cute baby you’re expecting. Over the next few weeks, you’ll start to feel these longer limbs as they continue moving. You may also start to see some movements through your bump, too.

 

Pregnancy at 23 weeks (Second trimester)

What’s happening in my body?

Now you’re over the half-way mark of your pregnancy, you’ll notice your baby really starting to grow. You may start experiencing some pain as your rib cage expands to accommodate your growing child. You’ll feel it even more so if your little one decides to practice some kung-fu, and jabs you with a wayward foot.

Being active and exercising can help you stay comfortable, and it’s especially good for back pain, which is common in pregnancy. The NHS recommends prenatal yoga or aquanatal classes (gentle exercise classes in water) with a qualified instructor. These can help build your muscles to better support your back.

You could also experience breathlessness as your baby grows. Your womb continues to push up, and will eventually impact the diaphragm, which is the muscle that sits under your ribcage and which controls your breathing. In turn, this also presses on your lungs.

You can help ease the feeling by standing upright (this also helps ease backache from carrying another person), or taking the weight off your feet completely and relaxing with a book or a movie.

Pregnancy symptoms in week 23

 

Infections

With more blood around your pelvic area, your body creates a milky fluid called leucorrhoea to keep your vagina clean and free from infection. If you notice it start to smell strongly, change colour or texture, then you may have an infection and should see your midwife.
Indigestion and heartburn
These digestive problems are caused by your baby growing into some of the space your stomach occupies, and your changing hormones.

Headaches

Those hormones are the likely culprits. Paracetamol is usually safe to take during pregnancy, but always at the lowest effective dose, and for the shortest possible time.

Feeling hot

With your body pumping more blood, and rampaging hormones, you can feel extremely hot. And not always in the best sense of the word. Wear loose, breathable fabrics and stay hydrated with chilled water.

Braxton-Hicks contractions

Braxton-Hicks contractions, also known as ‘false labour pains’ happen when the womb contracts and relaxes. It’s your body’s way of ‘rehearsing’ for birth and not something to worry about. Some women don’t even notice them.

Pregnancy anaemia

You’ll need extra iron for your baby. Signs of iron deficiency include feeling tired, and looking pale. Talk to your midwife about taking an iron supplement.

Focus on Calcium

Calcium is an important mineral, and should form a key part of your diet. Adult women need 700mg of calcium each day, whether pregnant or not – a reduction from the 1000mg recommended for adolescent females between 11-18 years old. According to one study, an adequate intake of calcium in pregnancy may also help to reduce the risk of pre-eclampsia and preterm birth. Thankfully, calcium is found in plenty of foods, including:

  • Calcium-fortified breakfast cereals
  • Dairy products, including pasteurized milk, yogurt and hard cheese, like cheddar (not soft blue cheese, or soft cheese with a white rind)
  • Fish with edible bones (like sardines)
  • Nuts and seeds, especially almonds and sesame seeds
  • Figs or dried apricots
  • Green vegetables like curly kale or spinach
  • Tofu
  • Calcium-fortified milk alternatives, such as certain oat milks

The body can’t make calcium, so it can only be sourced through diet. If you’re not getting enough calcium each day from your diet, your body will use its own stores of calcium, which could affect your bone health.

THE SCIENCE BEHIND CALCIUM

Powered by Nutricia

Ask anyone what calcium’s good for and you’ll hear ‘teeth and bones’. After all, that’s how 99% of calcium is used in the human body. However, you shouldn’t discount the remaining 1%. This tiny amount gets just about everywhere: Almost every cell in our body uses calcium in some way, and as your pregnancy develops, your body’s ability to absorb calcium increases.

This marvellous micro-mineral is also responsible for important functions like muscle contraction (including the heart), neurotransmitter secretion, digestion and blood clotting. Calcium also supports structures other than the skeleton, including membranes.
If you happen to be on thyroid hormone replacement medication while pregnant, tell your doctor or midwife immediately. Calcium and iron supplements can interfere with the absorption of your thyroid supplement.
