How big is my baby at 30 weeks? 

Your baby is fully developed, but there is still some fine tuning going on as the final pieces of the intricate baby-making jigsaw are put in place!

Your baby will measure around 39.9cm in length now, weighing nearly 2.9lbs and is continuing to put on weight. 

Should you go into premature labour, and your baby born premature, your baby would be taken to a special care baby unit, but they would have an extremely good chance of survival.

Their little lungs are not quite mature enough to support them in the outside world at this stage, and their brain is changing appearance wise, taking on the grooves and ridges that make it look the same as an adults'. These wrinkles will increase to provide more space for brain tissue to grow and develop.

It’s likely that if they aren’t already your baby will begin to move head downward and into the ‘engaged’ position. There’s around a litre of amniotic fluid surrounding the baby, but this will decrease as they continue to grow into the final weeks.

Facts to know about your baby in week 30

  • The Lanugo hair will start to disappear as the new brain cells and fat help to regulate the body temperature for the remaining weeks in the womb
  • A pint and a half of amniotic fluid surrounds baby, but that volume will shrink as they get bigger and takes up more room in your uterus
  • Their bone marrow is also starting to produce red blood cells ready for development and growth after birth
  • Your baby’s digestive tract is now almost fully developed and will soon be ready for mouth feeding after birth

You at 30 weeks pregnant

With the end nearly in sight, it could be nice to start planning a few little treats just for yourself before your baby is born. 

Getting your hair cut so it's in a nice easy to maintain style, or going for a pedicure (unless you are one of the lucky ones who can still reach her own toes!) could be nice ways to grab a bit of 'me time' before baby arrives. Or you could just have some girlfriends over for some pampering and get them to sort your tootsies out! 

It's not unusual around this point of your pregnancy to be experiencing weird dreams, but don't worry, it is completely normal, subject to when you manage to get to sleep with your ever growing bump.

Disturbed sleep could be the cause and when you wake straight out of your dream you're more likely to remember more detail of it. You can try light exercise or relaxation techniques to try and help your sleep or any worries and anxiety about the upcoming birth.

There are several other reasons you may be experiencing vivid dreams including the change in hormones in your body or your subconscious dealing with insecurities and fears you have about pregnancy and motherhood.

If you are suffering with worries and anxiety relating to your pregnancy, facing them may help ease the dreams. For example, if you're worried about getting to the hospital quickly when the time comes, do some practice runs at various times of day so you're clear which will be your best route can really help. Setting your mind at rest to it could free it from your subconscious.

Facts to know about you in week 30

  • From now you only need 200 calories a day more than before you were pregnant
  • The food you eat now travels more slowly through the intestines, to allow for better absorption. This can result in drier stools and constipation
  • The pregnancy waddle is due to the fact that joints become more relaxed and the centre of gravity changes
  • Due to the go-slow in your intestines, a build-up of gas is very common. Embarrassing, we know - but often unavoidable. Drinking lots of water can help
  • Your kidneys work much harder, they have to filter more blood. Your kidneys also make more urine as you get rid of waste for two
  • You are more prone to urinary tract infections in pregnancy. Report any pain, blood or burning to your doctor

What to think about in week 30

The big question for this week is have you packed your hospital bag?

 Now's the time to start thinking about getting organised for when you go into labour. Getting all the bits and pieces you need for your bag now will save you having to endure the shops in the last few weeks of pregnancy (which are reserved for feet-up style relaxing before 18 years of mummy-hood begins!). 

Your hospital bag needs to contain all the things you will need for the duration of your stay, so the items you might want in labour, such as lip balm, a comfy over sized t-shirt, your TENS machine and clothes and toiletries for after the birth. You'll also need to pack for your baby too, and choose what little outfit you want to dress them in after delivery, and their going home clothes! One of the best bits of pre-baby prep! You should also include maternity pads for mum, nappies, scratch mits and hat for baby. If you think you are planning to formula feed check with your local hospital regarding facilities after birth and what you need to take into hospital with you to do this.

Some units will have facilities to do this as there's been quite a change in the last few years. The majority of maternity units do not supply formula these days unless it is medically required. But some units do not have these facilities and parents are required to bring in ready-made formula and pre-sterilised bottles.

Thinking and researching what kind of birth you want is definitely an important consideration to start thinking about now you’ve reached week 30. 

Are you starting to find yourself fretting over how clean the floor is? Getting a random urge to clean the bathroom literally from top to bottom? Don’t worry, you’re not going mad, but you may be nesting.

You hear this term frequently in relation to pregnancy yet you may not be sure what it’s all about, and whether it really is a thing, but in simple terms, it’s when pregnant women, towards the end of her pregnancy, gets  a burst of energy and wants to clean and tidy her home really thoroughly. 

It’s actually been backed up by experts as in 2013 researchers at McMaster University in Canada found that the urge to nest stems from an inbuilt need in a mum to 'protect and prepare' for her unborn baby. So relax it’s quite normal, but don’t fret if it’s not struck yet either!
