A little less room, still plenty of growing 💛

Things are getting cosy in there. Your baby has less space to stretch, but there's still plenty of growing to do. Week 33 is a good time to keep preparing, one small step at a time.

📌 Week 33 at a glance

• Trimester: Third
• Baby's size: about the size of a pineapple, or nanas (around 43.7 cm head to heel)
• Still to come: roughly 7 weeks (a typical pregnancy lasts around 40 weeks)

🌱 Your little one this week

At 33 weeks, your baby weighs around 1.9 kg and measures about 43.7 cm from head to heel, roughly the size of a pineapple. The brain and nervous system are now fully developed, and the lungs are still maturing. The bones are hardening, apart from the skull bones, which stay soft and separate until your baby is around 12 to 18 months old. That slight flexibility makes the journey down the birth canal a little easier.

Your baby sleeps a lot, with periods of being awake and active.

🌷 And how about you, Mum?

You may feel your baby's movements as more like rolls and nudges now, as space gets tighter. You may also feel a heavy weight on your pelvis, which can be a sign that your baby is head-down and ready. Your womb may be practising with Braxton Hicks tightenings, which feel like a tightening over your bump for 20 to 30 seconds before relaxing. They shouldn't hurt, but if they become painful, or start coming at regular intervals, please contact your midwife or hospital in case labour is starting. Tiredness, backache, heartburn and needing the loo are all common, and some mums also notice swollen hands and feet, or vivid dreams.

If you notice a sudden or severe swelling of your face, hands or feet, severe headache, changes to your vision, or pain just below the ribs, please contact your midwife or doctor straight away. And as always, if you're ever unsure about your baby's movements, it's okay to call.

🍽️ Food for thought: B vitamins and everyday energy

B vitamins help the body release energy from food, and several of them support the nervous system. With energy dipping for many mums at this stage, it's nice to include a variety of foods that provide them.

Everyday foods that contain B vitamins include:

• Wholegrains such as brown rice, oats and wholemeal bread
• Eggs, milk and yoghurt
• Chicken, fish and lean meat
• Beans, lentils and leafy greens
• Bananas and avocados

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 resting with their feet up for a few minutes helps swollen feet
• Packing the hospital bag a little at a time can take the pressure off later
• A warm shower before bed may help you relax
• Writing down your birth preferences can help you feel prepared

🩺 Coming up

Babies do things in their own time, and only about 1 in 20 arrives exactly on the due date, so it's a good idea to have your hospital bag ready now. Common things to pack include your birth plan and hospital notes, clothes and nappies for the baby, something loose and comfy to wear in labour, spare clothes and underwear, nightclothes, nursing bras and breast pads, super absorbent sanitary pads, a wash bag and towels, healthy snacks and any medicines.

It also helps to save useful numbers in your phone, such as your hospital or clinic, your birth partner, the full address of where you're going and someone who can drive you, since it isn't safe to drive yourself in labour. Writing them down in your bag is a good back-up. A car seat for the journey home is also important. It's best to buy a new one, and to practise fitting and removing it.

You may like to ask your doctor or midwife about group B strep, a common bacteria that up to 2 in 5 people carry. It's usually harmless, but there's a small risk it can make a newborn unwell, and most infections can be prevented. Antenatal visits may be every two weeks now, and your doctor can talk with you about your birth preferences and when to come in. In Malaysia, you can ask your Klinik Kesihatan or private clinic about antenatal classes.

👨‍👩‍👧 Partner's corner

This is a great week to help with the hospital bag, check the route to the hospital and make sure the car seat is ready. And a little extra help around the house helps mum rest.

❓ Quick questions

Is it normal for movements to feel different now?
Yes. As space gets tighter, movements often feel more like rolls and nudges than big kicks. Your baby should still move regularly, so if you notice a change, please contact your midwife or doctor.

What goes in a hospital bag?
Your clinic or hospital can give you a list. Many mums pack comfortable clothes, toiletries, baby clothes, nappies and important documents.

💛 A little moment for the two of you

Thirty-three weeks. Your baby has less room, but just as much love around them.

Snug as can be, little one. 🦕
