The moment you begin to wonder if you need to be a dairy free breastfeeding mom is pretty scary. Your baby is showing weird physical symptoms the suggest you may need to eliminate dairy.

There’s likely mucus or blood in their diapers, they may be spitting up a lot, and you’re simultaneously grossed out, exhausted, and afraid.

I’ve been there, mama, and I can tell you that these symptoms are often signs of babies with a milk protein allergy. Dairy free breastfeeding is a common solution because milk protein passes through breastmilk to baby.

If you’re seeing these symptoms and want to go on an elimination diet, or if your child’s pediatrician has suggested your baby may have a food allergy to cow’s milk, it may be time for a diary free diet for breastfeeding.

Still unsure if baby’s symptoms are really allergic reactions? Contact your pediatrician for help.

Meanwhile, we’ve got you covered with all the signs of a cow’s milk protein allergy and tips for managing a dairy free breastfeeding diet.

Dairy Free Breastfeeding for a Milk Protein Intolerance

When my oldest kiddo was about 2 weeks old, I opened up a diaper to see an alarming amount of pink and red-streaked mucus. To say I was scared was an understatement!

Thanks to Doctor Google, followed by a call into the pediatrician’s office, I was able to boil it down to a probable milk soy protein intolerance.

The fix? Switch to hypoallergenic formula or transition to a dairy free diet for breastfeeding. Since my son had pretty severe colic, I was willing to try just about anything.

As a lifelong lover of all dairy products, this was a gut shot!

But we were young and formula was expensive, so I was hoping to nurse as long as possible. This led me to a full year of soy and dairy free breastfeeding.

Symptoms of dairy allergy in a breastfed baby

Before you make any drastic moves, know that a true dairy allergy isn’t that common. In fact, only 2.5% of children younger than 3 have a true dairy allergy.

Many babies and children do have a dairy intolerance, though, and the good news is that most grow out of it!

There are many ways to pinpoint a dairy intolerance, but the only sure way is by bringing a diaper to the doctor and having it tested.

Here are some common signs you might need to talk to your pediatrician about dairy free breastfeeding:

  • Mucus-y diapers. Basically mixed in with the “normal” poo, you’ll see what looks like little boogers in it. Gross, I know.
  • Blood in diapers. Nothing crazy – if it’s a lot of blood, please go to a doctor immediately. A dairy intolerance usually shows up as a streaks of red and pink mixed in with the previously mentioned mucus. 
  • Spitting up. And not happy spitting. We’re talking LOTS of spit up and uncomfortable, crying babies. The true sign of “too much” spit up is your baby is not gaining weight at a rate your pediatrician is comfortable with. 
  • Excessive gas. Is baby crying from lots of gas even though you burp well? It could be gas caused by a milk intolerance
  • Upset for long periods of time. This isn’t the best test because excessive crying could be the result of SO many issues, but if your baby cries for hours at a time regularly and has other symptoms of milk intolerance, talk to your pediatrician. 
  • Skin allergies. Finally, a big sign of a milk allergy is skin allergies like eczema. If you can deduce that excessive eczema isn’t from laundry detergents or scented soaps and lotions, this could be a good reason to try dairy free breastfeeding.

How long do you need to avoid dairy?

This was the first question I had when I started dairy free breastfeeding. Generally speaking, milk intolerance in babies rarely lasts longer than a year.

My pediatrician had me eat totally clean and dairy free for a year before introducing directly via solids, and my son was fine after that.

How to start dairy free breastfeeding

Okay, so you’ve decided that yes, you need to try a dairy free diet for baby.

But where on earth do you start with this daunting task?! You have to eliminate a lot of common foods to make your breast milk totally dairy free! I’ve got you covered with my best tips for removing cow’s milk from your diet.

(1) Figure out what dairy actually is

The first step to starting dairy free breastfeeding is to know what exactly you need to cut out. Diary has so many names that it can be confusing.

And just FYI: eggs are NOT dairy, which is a common misconception. Do your research and learn what you need to be cutting out.

Next, ask your pediatrician what the intolerance is. For example, if the intolerance is lactose, you’ll need to consume lactose free foods.

My son was intolerant to the proteins in milk, so I had to avoid every source of milk.

Note: It’s a common misconception that people who are allergic to milk are all lactose intolerant, but the two are very different, and understanding your baby’s problem is key.

Lactose is is a milk sugar, while casein is a milk protein.

A casein allergy occurs when someone’s immune system overreacts to the milk protein, while someone who is lactose intolerance is missing the enzyme lactase, which allows us to break down the milk sugar lactose.

(2) Learn to read labels

This goes hand in hand with learning what dairy is, but companies use many different words for cows milk.

Even if there isn’t a “this product contains milk” on the label, read the ingredients. The word “casein” is code for milk products.

I recommend this source for great information about reading labels to figure out which products contain cow’s milk.

(3) Ask questions

As a born people pleaser, this was so hard for me, so eating out just didn’t happen too often!

But if you’re eating out while dairy free breastfeeding, ask about what’s in your food.

Since I had to avoid both soy AND milk, this was super hard and important. Servers and restaurants are generally great at being helpful, especially if you can explain that your child is intolerant.

To help your servers help you, be very clear about WHAT you need to avoid and WHY.

I found specificity helped a ton. Saying “I can’t eat XYZ because it will make my baby very sick,” was a great way to bring attention to my issue.

Finally, if somewhere you want to eat is NOT willing or accommodating to you, stop going there. Seriously, that’s just rude.

(4) Give it time

When, in a few days, your baby still is miserable, you’ll probably want to give up and take a huge bite out of a wheel of cheese. Trust me, I know the feeling.

But know it can take up to 14 days for all dairy to leave your system! THEN give it another 14 days to make sure it’s out of THEIR system.

If, in that month, you don’t see ANY improvement to the way your baby reacts to your milk, talk to your pediatrician about your options.

I ALWAYS recommend that moms trying out dairy free breastfeeding also cut out soy for the first 4 weeks. This way, you’re not stuck going through the first month with little improvement and having to wait another month to test out removing soy.

Soy and milk proteins interact with the body very similarly, so many babies who require dairy free milk also need soy free milk.

Finally, know that once you get the bulk of milk and soy out of your system, single slip ups tend to take less time to leave the body.

So while it might take a month to “get clean” at first, I found a couple of days were all that was needed after a slip up. Thank goodness.

(5) Find substitutions

This is the most important thing to do to be successful with removing milk from your diet.

There are SO many options now for dairy free products – more than there were even 6 years ago when I needed them. There’s almond milk, coconut milk, and even milk made from peas! Just be sure your baby doesn’t have additional allergies that would require you to avoid other types of foods.

Try out multiple coffee creamers (we love Califia & Nutpods unless your baby also has a nut allergy), ice creams, and cheeses to find one you like.

I actually used it as an opportunity to learn how to make things myself, like bread and tortillas. (most have at least soy in them, if not also milk. It’s why you need to always read the labels!)

I loved the Spectrum line of butter and shortening for baking.

(6) Subscribe to Thrive Market

Admittedly, this is directly connected to finding substitutions. But Thrive Market lets you shop by diet, so you can tell it up front that you need all ingredients to be dairy free and soy free.

Also, finding good dairy free and soy free alternatives often means buying specialty products. Some may be hard to find in your local stores, depending on where you live. But even if you have access to them, they’re pricey.

Thrive Market requires an up-front subscription, but then cuts your grocery bill nearly in half on all these specialty products. And with this link, you get a $20 credit with membership.

Dairy Free Breastfeeding is not for me; what should I do?

First off, lose the guilt. Going dairy free when you’re used to it is HARD. SO HARD. Especially if you love all things diary.

If it’s just not working, there’s a few things you can do – first: TALK TO YOUR CHILD’S PEDIATRICIAN.

I cannot stress this enough.

They might give you suggestions about alternatives, like testing to make sure it’s a milk intolerance and not something else.

You can also try a dairy free formula. Yes, they can be more expensive, but see if your pediatrician has samples and if your insurance covers it. You have to order online in the US, but HiPP is by far our favorite formula brand.

At the end of the day, you have to make sure that your child is healthy and happy, but that you are also healthy and happy.

Give dairy free breastfeeding a shot, and if it doesn’t work out, do your homework on other options. You can do this, mama!
