You are probably feeling as if you've reached a significant
milestone by this stage. Getting to the start of your third
trimester really is the beginning of the countdown to when you will
be having your baby. Officially, the third trimester relates to the
weeks between 28 - 40 of gestation. There can be a week or two of
variation though, depending on the source.
This is the trimester when all of your baby's organs and systems
will be preparing for extra uterine life. Although they have been
fully formed since 12 weeks, an enormous amount of maturity and
development has been taking place since then. Your baby's movements
will become stronger, more defined and less subtle than they have
been. As your baby grows, less room will be available for it to
move freely, so kicks and obvious changes in its position will all
be clearly felt by you.

Time to Unwrap Some Presents!
It's baby shower time. If your friends and family want to put
one on for you, accept their offer in the spirit that it's made.
Showers can be a lot of fun. It will also give you an opportunity
to get together with people who you may not have time to catch up
with after the baby is born. If you don't like being the centre of
attention or worry that you'll feel awkward, just aim to keep it
low key. Everyone loves a baby and gets excited when one is coming.
Remember, this is your chance to have a little pampering for all
your hard work growing your baby.
Now, Where Did I Put That Suitcase?
This will be the time you need to think about packing your
hospital bag. Try to remember you won't be going away for a month
and be practical with what you include. Toiletries, maternity pads,
nightdresses and comfortable day clothes as well as nappies and
clothing for the baby are some of the essentials. If you plan to
bottle feed, you'll need to take formula, bottles, caps and newborn
teats as well.
At some stage, sit down with your partner and make a list of the
people you will want to contact when the baby is born. Straight
after birth is not the time to be searching for telephone numbers
or giving your partner instructions on where at home you've written
them down.
You're Having a Little Holiday Too
Make clear arrangements with another trusted adult regarding who
will be minding your older children when you have the baby. If your
partner is going to stay with you at the hospital, you may even
need to make arrangements to have your pets cared for.
Apart from just being a time when the baby is finally maturing,
the third trimester really is the time for organising
practicalities. Make lists, cross them off as you do things, write
important dates on your calendar and generally try to keep on track
of things. You can avoid a lot of anxiety and stress just by being
organised.
Your Physical Changes in Your Third Trimester
- You are certainly going to get bigger in the third trimester.
Your tummy is growing upwards and outwards, making deep breaths a
thing of the past. You'll be feeling increasingly bulky, breathless
and swollen, not a great combination really.
- Some women carry their pregnancy neatly, as if they have popped
a basketball under their jumper. Others seem to spread from their
front to their back and around again. It really depends on
individual shape and size and your baby's growth. There is no one
way to appear.
- The third trimester is when the risk of complications can peak.
Pre-eclampsia, gestational diabetes, hypertension, bleeding or
problems with the amniotic fluid can all occur. This is one of the
reasons why your ante-natal checks will increase in frequency.
- You could feel unsteady on your feet and become more prone to
falling. Avoid wearing high heels and take your time getting to
where you want to go.
Your Emotional Changes in Your Third Trimester
- You will tire more easily during your third trimester and feel
the effects of nurturing your growing baby. As you get closer to
term, you may feel exhausted on some days and totally fed up with
being pregnant. This will undoubtedly have an effect on your mood
and how you feel generally.
- You could become increasingly concerned about the labour and
delivery. The concept of the unknown and leaving things to see how
they turn out may not bode well with you, especially if you
normally like to feel you are in control and have everything
sorted.
- You may be placing a significant emotional investment into
planning a natural, drug free labour and delivery and building your
hopes on this. Keep an open mind and try to remember that although
the majority of births proceed without complications, there is
always the possibility that intervention may become necessary.
- Invest some time and energy into writing up your birth plan.
Include your partner's wishes and how you feel he could best
support you. If you are considering having a doula or other support
people present, talk with them about how you both see their role.
Remember that labour can be unpredictable and despite planning,
there are often unforeseen events which can occur.
- You may seriously start to wonder how you are going to cope
looking after a new baby. If you have other young children whose
demands on you are high, the thought of caring for another child
may seem overwhelming. Talk with your partner and organise some
early supports within your family and friends.
Your Baby's Changes in Your Third Trimester
As your baby progresses past 30 weeks of gestation, its chances
of survival, if it were born, are much better than in the previous
weeks. For every day it remains in your uterus, its body systems
are further maturing towards independent life.
When you have your ante-natal checks, don't be alarmed if your
baby is lying in any other position than head down. It is not
uncommon for baby's to prefer to lie in the breech position early
in the third trimester. This may cause you some discomfort
underneath your ribs. Instead of a nice round bottom nestling under
your ribcage, a hard bony skull is making its presence felt.
Hints for Your Third Trimester
- Rest and put your feet up when you can. Don't push yourself.
Try to have a daytime rest everyday and nurture your body.
- Get the nursery ready. Wash and fold those tiny clothes and
take pleasure in nesting for you little one. Take a moment, each
day to just sit in your baby's room and think about how your new
life will be when you have your baby. This is a lovely thing to
do.
- Eat when you are hungry, stop when you are full. You probably
won't feel like big, heavy meals, there's just not enough room for
your stomach to hold much anymore. Remember to drink at least 2
litres of water every day to keep you well hydrated and your mind
alert. Don't venture too far from a toilet; it will become your new
best friend in the third trimester.
- Read to your baby every day, this isn't as crazy as it sounds.
Your baby will also hear music, your partners and other children's
voices and everyday domestic noises as well.
Weekly Development
Your baby is over 1 kilogram this week. Your baby's head is in
proportion to its body and it's looking more like it should.
There's been lots of brain development in its sleep processes and
is starting to have REM (Rapid Eye Movement) sleep phases
from this week forwards. Dream on little baby.

Your baby has gained 300-400 grams this week. This is one of the
reasons why so much of its time is spent sleeping; to conserve
energy and lay down its fat stores.

Your baby's brain is maturing at a fast rate this week, so eat
lots of brain food and head to the fish market. Remember to avoid
eating fish which can contain high levels of mercury. Think of fish
which are predatory to others and which are higher in the food
chain. These are the ones you need to avoid.

If your baby is born now, it would probably be able to manage
pretty well without too much intensive or special care. Its
temperature regulating ability wouldn't be too good, so it would
still need to be in a humicrib which would help it to maintain an
even temperature level.

Your baby is spending a lot of its time sleeping. When it is
awake you may see your tummy rolling as it changes its position.
You may see the odd elbow or knee poke you and feel it hiccoughing
away. There's a lot going on.

Your baby is gaining lots of weight this week, up to around 450
grams. That's a lot, considering an average weight gain for a
newborn in the first few months is 150-200 grams/week.

Your baby's skin is very red and still a little loose. Your baby
is blinking, moving, grabbing and grasping. It doesn't know it's
doing these things of course, conscious thought and intent is still
months away. It's also having regular cycles of rest and
activity.

Your baby is around 50 centimetres long this week. Your baby's
brain is developing at an enormous rate. Eat foods high in DHA (Docosahexaenoic
Acid), such as cold water fish. Speak with your midwife or doctor
about needing to take a daily supplement of this important fatty
acid.

From this week it could engage in your pelvis and you may feel a
sense of it "dropping" lower. This means more breathing room for
you, but more pressure on your bladder. If this is your first baby
though, it is not unusual for it to engage in the pelvis until
labour has already started.

If your baby was born now, its lungs would be able to work
effectively. It would be able to breathe on its own and not require
support.

From this week on, your baby is considered term. It may be born
anywhere from now on, so be prepared. Its skin looks less wrinkly
and has more of a visible layer of fat underneath it. The vernix
which has been covering it starts to be reabsorbed.

It's all systems go from now on. Your baby is virtually ready
for independent life and is preparing for birth. It is still
gaining a little weight and its brain is still maturing. If you are
going to have a booked caesarian section delivery, this will often
be the week it is planned for.

You're there, ready at any stage to have your baby. Don't worry
if you still haven't got your mind around it, lots of mothers feel
this way. It's not entirely clear what causes the onset of labour.
One theory is that the baby emits a particular protein which causes
the mother to start contracting.

You're probably short tempered even with your own shadow this
week, waiting in anticipation for "D" day. Even though your due
date has come and gone, don't feel as if you're experiencing
humanity's longest gestation.

Being overdue to have a baby means different things to people.
Some pregnant women will be quite relaxed about it, confident that
the baby will come in its own sweet time. Others are anxious,
waiting nervously for something, anything to happen.
