By Chelsea Long, Whole30 Content Manager, sharing five tips for a breastfeeding Whole30.

Raise your hand if you’re breastfeeding, Whole30’ing and wondering how to keep your milk supply up.

Judging by our Instagram DMs (where this question is asked in some form very often) I’m imagining a sea of people with their hands high in the air. I see you, and I’m here to help.

While the materials in our Pregnancy Program end just after the labor and delivery stage of pregnancy, our team is committed to helping people in the Whole30 community figure out how to have healthy, happy pregnancies at all stages, including postpartum (what’s commonly called “the 4th trimester”). We’re currently working on our postpartum program, but until then I’ve assembled our best advice for a successful #BreastfeedingWhole30.

Tip #1: Eat enough food

This might seem like one of those, “well, duh!” statements, but stay with me. Many nursing people have reported that they need four full-sized meals daily, following the Whole30 Meal Template, to keep up with their hunger. Now is a good time to remind yourself what the Whole30 Meal Template includes, because we often find that people tend to under-eat during a Breastfeeding Whole30.  Here are a few things we like to point out:

  • If eggs are your protein of choice, as many whole eggs as you can hold in your hand, which is probably 3-4.
  • You generally want at least one fat serving in addition to what you cook in, since cooking fat often remains in the pan and isn’t consumed.
  • Aim for 2-3 cups of veggies at every meal and add more if it’s all raw leafy green stuff as they tend to wilt down and aren’t very substantial. Occasionally, have some fruit–a fist-sized serving up to a couple of times a day.

If you’re balking at the idea of eating four full meals a day, remember, weight loss is not the goal during a #BreastfeedingWhole30. You can try having three full meals and one mini-meal that includes a smaller portion of protein, veggies, and fat. Experiment with eating asparagus, green beans, carrots, yam, watercress, sweet potatoes, dandelion greens, peas, beets, parsley, sesame seeds, avocados, raw almonds, cashews, macadamia nuts, garlic, onion, ginger and other leafy green vegetables, as these foods may help with increasing milk supply.

The Whole30 is all about self-knowledge, so stay observant about how what you eat impacts your body. Also, stay observant about how what you eat impacts your baby. Certain veggies (such as cruciferous veggies and onions) have been known to cause gas in some sensitive babies. This doesn’t mean you need to restrict your intake of these foods.  Just watch out for any signs of uncomfortable gas or fussiness in your baby, especially if you’ve drastically increased your intake of those foods.

Tip #2: Stay hydrated

In general, we recommend that you drink a lot of water during your Whole30. You can calculate the minimal amount of water you should drink by taking your body weight, dividing it in two, and then taking that number and drinking that many ounces of water a day. (For example, if you weigh 140 pounds, you should drink 70 ounces of water a day). Remember, this is the MINIMUM. Many people report that they need to drink more than this. Consider adding Himalayan Pink Salt, Sea Salt or LMNT Recharge (Note: only their unflavored variety is Whole30-compliant) to your water to make sure that your body properly hydrates.

Easily bored with “just water”? I’m right there with you. A few ideas to help you get your recommended daily water intake:

  • Divide the number of ounces required per day by your waking hours and set a goal to drink a certain amount of water per hour.
  • Drink a glass of water before drinking any other kind of liquid (such as sparkling water or kombucha).
  • Sip on coconut water or mix it with lime sparkling water and fresh lime juice for a special treat.
  • Drink herbal teas throughout the day, especially teas that contain fenugreek, blessed thistle, fennel, stinging nettle, goat’s rue, alfalfa, milk thistle, anise, marshmallow root, red raspberry leaf, coriander, caraway, and verbena. Some babies may react to some of these teas, so be observant and discontinue use if it’s not working for you and your babe. Always check your labels to make sure the tea is Whole30-compliant.
  • Mix it up by making yourself a fun, hydrating mocktail like these:

Tip #3: Eat starchy vegetables

We’ve heard from lots of Whole30 community members who say eating starchy vegetables at least two of their meals per day helps them keep up their milk supply. Here are just a few yummy recipes that include starchy veggies to get your kitchen creativity going:

Tip #4: Don’t skimp on healthy fats

On the Whole30, fat is not your foe! In fact, during a #BreastfeedingWhole30, you may want to increase your intake of healthy fats. This may help keep your milk supply rich. You can sip on coconut milk throughout the day or make smoothies* that include fat-rich avocados and nuts. Try this Whole30 Coconut Blended Coffee from Amanda of the Kitcheneer. Another great idea is to add homemade (or store-bought!) mayo to your breakfast potatoes. Here’s a great recipe for one-minute mayo from Cristina of Castaway Kitchen.

Eat all of the avocados. In case you need a few ideas of what to do with avocados, here’s some recipes we love:

*A note about smoothies: yes, you’re right… smoothies are not typically encouraged during a Whole30, but remember, that’s a recommendation and not a Whole30 rule. Technically, they are compliant. In the case of a #BreastfeedingWhole30, if this is a good strategy for you to work healthy fats and nutrients into your diet occasionally, go for it! Just try limiting the amount of fruit to one cup and don’t use them as a dessert replacement/ SWYPO.
