Breast milk is best for your baby
The World Health Organisation recommends exclusive breastfeeding for the first six months of life. Unnecessary introduction of bottle feeding or other food and drinks will have a negative impact on breastfeeding. After six months of age, infants should receive age appropriate foods while breastfeeding continues for up to two years of age or beyond. Consult your doctor before deciding to use infant formula or if you have difficulty breastfeeding.

The Journey of Pregnancy: Your Little One’s Development, Month by Month

Let’s take a peek inside your womb to see how your little one develops from month to month. Check out more info here!

That’s it, you’re pregnant! Congratulations are in order. But now, you’re curious about how your little one is going to develop in your belly. What will he or she look like as they grow inside your belly? How will you feel when they move and kick about? Let’s take a peek inside your womb to see how your little one develops from month to month.

 

Conception: how does it start?

When the sperm meets and penetrates the egg, it’s called fertilisation. It’s also known as conception! At this moment, the genetic makeup is complete, and that includes if your little one is going to be a boy or a girl! Within three days after conception, the fertilised egg is dividing itself very fast into many cells. It passes through the fallopian tube into the uterus, where it attaches to the uterine wall. The placenta, which will nourish your little one, will also start to form.

 

What’s going on at 4 weeks?

At 4 weeks or one month, your little one is developing the structures that will eventually form into their face and neck. The heart and blood vessels will continue to develop. The lungs, stomach and liver start to develop. If you try out a pregnancy test now, it will show up as positive!

 

What happens after 8 weeks?

Your little one is now a little over half an inch in size! Their eyelids and ears are forming, and you can also see the tip of the nose. The arms and legs are well-formed, and the fingers and toes grow longer and more distinct.

 

What’s happening at 12 weeks?

Your little one has grown about 2 inches now and they will also start to make their own movements. You may feel the top of your uterus above your pubic bone. Your little one’s heartbeat can also be heard now, via a doctor’s special instruments. Your little’s one sex organs should also become clearer.

 

It’s Week 16 now!

Your little one should now measure about 4.3 inches to 4.6 inches. You should be able to feel the top of your uterus about 3 inches below your belly button. Your little one can now blink, and their heart and blood vessels are fully formed! Their fingers and toes also now have their own fingerprints.

 

Pregnant for 20 weeks. What now?

Your little one should weigh about 10 ounces now and is a little more than 6 inches long. Your uterus should be at the level of your belly button. Your little can now also suck a thumb, yawn, stretch and even make faces! Very soon, if you haven’t experienced it already, you can feel your little one move inside your belly, which is also known as “quickening”.

 

It’s time for an ultrasound, mummies!

At around week 20 for pregnant women, it is usually time for an ultrasound. During this ultrasound, your doctor will make sure that the placenta is healthy and attached normally – and that your little one is growing properly. You can see your little one’s heartbeat and movement of their body, arms, and legs on ultrasound. You can usually find out if your little one is a boy or a girl during this time.

 

On to 24 weeks of being pregnant!

Your little one should now weigh about 1.4 pounds and responds to sounds by moving or increasing their pulse. You might even notice jerking motions if they hiccup. With their inner ear fully developed, your little one may also be able to sense being upside down in the womb.

 

What’s up at 28 weeks?

Your little one should now weigh about 2 pounds and 6 ounces, and they position often at this point in pregnancy. It’s possible to experience premature labour now, so ask your doctor about pre-term labour signs. Now, it’s time for you to register for birthing classes. Birthing classes can prepare you for many aspects of childbirth – this includes labour, delivery, and taking care of your new-born little one.

 

32 weeks! Almost there!

Your little one weighs 4 pounds and moves around often. Their skin has fewer wrinkles as a layer of fat starts to form under the skin. Between now and delivery, your little one will gain up to half their birth weight. Ask your doctor how to do a foetal movement chart. Think about breastfeeding. You may also notice a yellowish fluid leaking from your breasts. Don’t worry; that’s colostrum, and it happens to get your breasts ready for making milk. Most mummies go to their doctor every two weeks at this stage of their pregnancy.

 

Development at 36 weeks; it’s the endgame!

Depending on many factors, your little ones differ in size. These factors include gender, size of the parents, etc. Your little one’s rate of growth is as important as the actual size. On average, little ones at this stage is about 18.5 inches and weigh close to 6 pounds. The brain has been developing rapidly. Lungs are also nearly fully developed. The head is usually positioned down into the pelvis by now. Your little one is considered at ‘term’ when they are at 37 weeks. They are at an early term between 37 to 39 weeks, at term, if they’re 39 to 40 weeks and late term if they’re 41 to 42 weeks.

 

Happy birthday!

A mummy’s due date marks the end of their 40th week in their pregnancy journey. The delivery date is calculated using the first day of their last period. Based on this, pregnancy can last between 38 and 42 weeks with a full-term delivery happening around 40 weeks. Some post-term pregnancies – those lasting more than 42 weeks – are not really late. The due date might not just be accurate.

And that’s it! We hope this month-by-month playbook will help you on your pregnancy journey. As with many guides, accurate numbers and dates may differ, depending on the mummy. But if you have any burning questions about your little one or your pregnancy, be sure to check with your doctor for more information.
