Breastfeeding while pregnant. Everything you need to know. Mom with baby.

Can You Still Breastfeed If Pregnant?

Yes, you can absolutely still breastfeed while you are pregnant. Your body will continue to produce milk for your older child, while still giving enough nutrients to your baby.

Does Breast Milk Change While Pregnant?

About half way into your pregnancy, your body will start to prepare for your new baby by producing colostrum. Your breast milk might taste different to your child, and they might start weaning themselves off of breast milk by themselves.

If you child is under 12 months old, they depend on your breast milk, so if they do not like the new taste and start weaning themselves, make sure they are still growing. If they decide they do not like the taste of your breast milk, you may have to supplement with formula.

Don’t worry, even if you continue to breastfeed your older child while pregnant, there will still be enough colostrum for your new baby when they are born.

Can Breastfeeding While Pregnant Cause Miscarriage or Preterm Labor?

When you breastfeed, your body releases the hormone, Oxytocin, which is also released during labor to cause uterine contractions.

The amount of Oxytocin that is released while breastfeeding is very minimal, compared to the amount that is released during labor, and will not be enough to cause a miscarriage or preterm labor.

However, is you have a high risk pregnancy, are pregnant with twins, or are advised to not have sex during pregnancy, then your doctor might advise you to start weaning your child from breastfeeding.

Breastfeeding While Pregnant Diet

Whether you are pregnant, breastfeeding, or both at the same time, you want to make sure you are eating a healthy diet and drinking plenty of fluids.

Above all, make sure you listen to your body. Eat when you are hungry, and drink when you are thirsty. Remember, your body is responsible for giving nutrition to help grow both a baby and a toddler, so a nutritious diet is a must.

Pros and Cons Of Breastfeeding While Pregnant


It is now recommended to breastfeed a baby until they have reached the age of two, so if your toddler is still under 2, there are many benefits of continuing to breastfeed them for their growth and development.

You will feel like a champion!! Having a toddler can be overwhelming and stressful at times, and being pregnant can be exhausting. Now add pregnancy and breastfeeding together, and you might feel like you can’t even make it through the day.  

But if you are breastfeeding while pregnant, two lives depend on you and your body, and there is no greater feeling than knowing that you have two babies that are growing and developing because of the hard work that you are putting in.


Increased Symptoms

Pregnancy comes with enough annoying symptoms, and breastfeeding while pregnant can be known to increase these symptoms. Morning sickness could be worse if you are still breastfeeding.

Also, pregnancy hormones cause nipple soreness, and breastfeeding can irritate this even more.

Breastfeeding Aversion While Pregnant and Beyond

A pregnant woman feels sick, sore, and tired, and having a toddler climb on top of you all the time can get irritating. Many moms find themselves getting annoyed by having to breastfeed an older child while pregnant.

This can also last (or increase) after your second baby is born, because you might get more joy out of breastfeeding your little tiny baby compared to your big wild toddler.

This is completely normal to feel that way, and it can get better over time.

Milk Supply

Many times your milk supply will decrease during pregnancy. This can be due to the fact that your body is producing Progesterone when you are pregnant.

Breastfeed and pump as much as possible to let your body know you want to increase or keep your milk supply.

If you notice your milk supply is decreasing make sure to supplement with formulas or other foods, so your child is getting all the nutrition they need.

Tips For Breastfeeding While Pregnant

1. Weaning

If you plan on weaning your toddler from breastfeeding, make sure to do this before the new baby is born.

If you try to wean your toddler after your baby is born, they will see the new baby breastfeeding and get jealous.

2. Tandem Feeding

If you plan on tandem feeding, make sure to talk to your child about having to share in the near future.

Up until this point, your toddler has been breastfeeding by themselves, and it could be something that makes them feel safe and comfortable. When it comes time to share, they might have a difficult time.

3. Colostrum

It is important that your new baby gets colostrum the first few days after they born.

Focus on breastfeeding your new baby right after they are born. Have someone else take your toddler away, so they do not get jealous or want to join.

You can always pump before labor and delivery, so you have breast milk to give your toddler during this time.

4. Freezer Stash

If you are planning on getting pregnant with a second child while you are still breastfeeding, make sure to start a freezer stash of breast milk, so you can use this when times get tough during your breastfeeding while pregnant journey.

5. You Can Do It

If your goal is to breastfeed through your pregnancy and tandem feed, just remember it is possible!

When times get tough, don’t give up. Pregnancy does not last forever, and things will get easier. You only have a very short period where you get the opportunity to breastfeed your children, so make it count no matter how difficult it may seem.

6. It’s Okay If You Can’t

It is okay to stop breastfeeding your toddler.

If things get too difficult, remember there are always other options, and this is perfectly acceptable.

7. Annoying Comments

Prepare for annoying comments.

Many other people will not understand your situation, and they will make rude comments. People will question why you are continuing to breastfeed your older child, or they will wonder why you got pregnant again so fast.

I will not sugar coat it, breastfeeding while pregnant is difficult, but other people will not understand what you are doing or why you are doing it. Their opinions do not matter. The only thing that matters are you two children and what is best for them.

8. Feeding Position

You might need to change your feeding position.

As you get further along into your pregnancy, your baby bump might get in the way when trying to breastfeed your toddler.

Pregnancy can also cause back pain, and it could be difficult to get comfortable when trying to breastfeed your child.

You might have to experiment with different breastfeeding positions, and decide what works best for your new situation.

The more your children eat, the more milk you will produce!
