Breastfeeding During Pregnancy

Who knew that a woman’s body can be both growing a baby and feeding another one at the same time? That is amazing!!!! I was just under 7 months postpartum with my first baby when I became pregnant with my second. Yes, by that point your baby should be introduced to solids, but they are still very much dependent on milk. And if you are exclusively breastfeeding, that means you will experience breastfeeding during pregnancy.

Does breastfeeding during pregnancy affect the baby?

According to La Leche League’s website, it is considered safe both to your unborn baby and older baby to breastfeed during pregnancy.

When I was doing “double duty”, I still made a point to let both my OBGYN and our pediatrician know. That way, each doctor is notified and then can share any specific information that they may have.

You will most likely be able to continue on with your regular dosage of prenatal vitamins versus “doubling up”. But it never hurts to ask your OBGYN if they recommend any additional supplements during this time.

This is the prenatal I am currently taking. I have experimented with several brands, and this is the only one so far that DOESN’T make me want to throw up when taking it (hello, first trimester!) or has a weird aftertaste.

When should you stop breastfeeding during pregnancy?

As long as both babies and your health are all good, there is no need to stop at any point during pregnancy.

Some mothers even breastfeed both children when the youngest is born which is called “tandem nursing”.

You may experience a dip in your milk supply once you become pregnant, which may or may not bother your older child.

Typically, around the 4th or 5th month of pregnancy your breast milk will start tasting different. It will probably be less sweet as your body is getting ready to produce colostrum again.

For some children, this change in taste will turn them off to nursing and wean themselves off. But others will keep on trucking! For my oldest, he was very close to being weaned by my 5th month, so it is hard to know personally if it was the taste change or he was just ready to be done.

Taking care of your health is now more important than ever

This is something I wish I grasped when I was breastfeeding during pregnancy. When you eat, take vitamins, exercise, and sleep, you are doing this for THREE people: your nursing baby, baby on the way, and you!

That is a lot for your body to do!

This is totally doable, but that means you have to put your health at the highest priority. Focus on foods that are high in protein, healthy fats, and fiber to give everyone the best nutrition possible.

I was SO hungry that I felt like I ate like a football player. But I wish I worked harder at finding the healthiest options so then I had more energy and felt better.

Please, take naps when you can. In the moment you probably don’t realize how hard your body is working but you need so much rest!

Hang on to that freezer stash!

As you get closer to giving birth, make sure to go through your freezer stash of frozen breast milk.

Frozen breast milk can last in your freezer up to 6 months. So go through your stash and toss/donate what is about to go bad but keep any that will still be good for when your next baby is born. You’re already a step ahead of the game!

Having a hard time tossing milk? I get it-that’s liquid gold baby! Even if your older child is weaned, you can still incorporate milk into their food such as oatmeal.

I did that a lot, and your child probably won’t even bat an eyelash. Phew!

Check if you are eligible for a new breast pump

Through most insurance plans, you should be eligible for a new breast pump every year. When I gave birth in 2019, I was again able to get a new pump for my 2020 baby.

Why would you want a new breast pump?

There’s a good chance that you put some miles on your old breast pump and could stand some new valves and other parts too. If your older pump is still in good condition, then you can have TWO pumps for your next baby. One to keep at home, one to keep at work or in your car!

Plus, you may want to try a different style or brand of pump-now’s your chance to try it out. I recommend working with Aeroflow to figure out insurance. It’s free and they make it so so so easy.

Breastfeeding during pregnancy almost seems impossible, but you can do it! God designed women’s bodies to do amazing things! Along the way if you decide to wean your oldest, that is completely okay too. Be proud of the work that you have done and continue to do for your children, no matter where you end your breastfeeding journey.
