👶Your baby this week
Your baby is now about the length of a small nappy, roughly 28.9 cm from head to heel and beginning a major growth spurt that will continue over the next few weeks.
Baby’s skin is still thin and slightly wrinkled but takes on a pinkish tone as veins and arteries form beneath the surface.
Fat deposits are beginning to build, helping the baby fill out and regulate temperature later in pregnancy.
Lungs are developing and baby is practising tiny breathing motions, moving amniotic fluid in and out to strengthen the respiratory system.
Your little one’s limbs are now in proportion and getting stronger, you may soon see kicks or rolls ripple across your bump.
Baby’s hearing is improving daily, recognising sounds like your heartbeat, voice, and even external noises.
The placenta is now fully functional as baby’s life-support system, delivering oxygen and nutrients while removing waste.
A pattern of sleeping and waking is becoming established, though it may not yet match your rest schedule!
🌸Your body this week
Around week 23, your bump is growing rapidly, and you may notice more distinct movements throughout the day and night.
Breasts may begin leaking small amounts of colostrum, a thick, yellowish pre-milk packed with antibodies that will nourish baby after birth.
As the uterus expands, you might feel rib pain or shortness of breath when baby presses against the diaphragm.
Hormonal changes can cause nasal congestion, mild nosebleeds, or gum sensitivity.
Stretch marks may appear as skin stretches across the tummy, breasts, and hips – moisturising can help ease any dryness or itching.
💛Symptoms you might notice
Every pregnancy is different. These are common around week 23 — speak to your midwife if anything worries you.
Back Pain
A growing bump and shifting posture can strain back muscles. Maintain good posture, wear supportive shoes, and use cushions for comfort when sitting.
Rib Pain or Breathlessness
Baby’s growth can press on your ribs and lungs. Take regular breaks to rest, practise deep breathing, and elevate your feet to ease pressure.
Heartburn & Indigestion
As pregnancy hormones relax muscles, stomach acid can rise more easily. Eat smaller meals, avoid lying flat after eating, and reduce spicy or fatty foods.
Swelling & Tingling Hands
Mild swelling (edema) is normal, but take breaks to move around, elevate feet, and stay hydrated. Tingling hands can signal pressure on wrist nerves, make sure to stretch regularly if working at a desk.
Bleeding or Sensitive Gums
Hormones can inflame gums. Brush gently, floss, and schedule a free NHS dental check during pregnancy.
Snoring
Nasal congestion and pregnancy weight can increase snoring. Use a humidifier or nasal strip and sleep on your side to improve airflow.
Tiredness or Pregnancy Brain
Hormones and disrupted sleep may cause forgetfulness. Make lists, keep hydrated, and rest when possible.
Braxton Hicks Contractions
Mild, irregular tightening across the bump is normal preparation for labour. If they become painful or regular, contact a midwife.
✨Tips for week 23
Bond with Baby
Talk, sing, or play gentle music to your bump. Baby can hear familiar voices and may respond to sound or touch.
Stay Sun Safe
Pregnancy hormones make skin more sensitive. Use SPF 15+ with 4-star UVA protection, cover up, and avoid strong midday sun (11am–3pm).
Whooping Cough Vaccine
If you haven’t had it yet, the pertussis jab is recommended between weeks 16–32. Immunity passes through the placenta, protecting baby until early vaccinations.
Cut Back on Caffeine
Aim for under 200mg of caffeine daily. Swap coffee or tea for herbal alternatives or smoothies to stay hydrated and energised.
Pelvic Floor Exercises
Daily squeezes (as if stopping mid-pee) strengthen muscles to support your bladder and uterus, reducing the risk of leaks later in pregnancy.
Healthy Eating
Eat a balanced diet rich in fruit, veg, wholegrains, and lean protein. Avoid eating for two, extra calories aren’t needed until week 28.
Exercise & Rest
Aim for 150 minutes of moderate activity each week, like walking or swimming. Balance this with rest and short naps to manage fatigue.
Vitamin D
Continue a 10-microgram daily vitamin D supplement, especially between October and March. Some people should take it all year round, check with your GP or midwife.
Look After Mental Health
It’s normal to feel anxious or low at times. Create a wellbeing plan using Tommy’s online tool and talk openly with your midwife or doctor if struggling.
When to Seek Medical Help
Call your maternity unit immediately for heavy bleeding, severe pain, vision changes, sudden swelling, or reduced baby movement.
