As natural as nature intended

Breastfeeding is a powerful, natural way to nourish and bond with your baby—but that doesn’t mean it’s always easy, predictable, or stress-free. Whether you’re wondering what to eat, how to protect your milk supply, or how to store breastmilk safely, this guide has you covered.

We’re here to answer your most common questions with compassion, science-backed info, and zero judgment—because you’re doing something amazing, and you deserve support every step of the way.

🥦 Nutrition & Breastfeeding: What You Eat Matters (But Not in the Way You Think)

Your body is brilliantly designed to make high-quality breastmilk—even when your diet isn’t perfect. It will pull nutrients from your own reserves to give your baby what they need. But eating well helps you just as much as it helps your milk.

Balanced nutrition supports:

  • Your energy and mood
  • Milk volume and let-down
  • Recovery after birth
  • Your baby’s exposure to nutrients and flavors

Let’s break it down with no pressure to eat a kale salad at 3 a.m.

💧 Hydration Tip: Breastmilk is 90% water. Aim for 8–12 cups of fluid per day. Drink to thirst, and keep a water bottle nearby when feeding or pumping.

✅ Do’s & ❌ Don’ts of Breastfeeding Nutrition

✅ DO:

  • Eat a variety of whole foods
  • Include snacks with protein and healthy fats
  • Take a postnatal vitamin
  • Stay hydrated
  • Prep meals/snacks for easy access
  • Listen to your body—you may need more calories
  • Consult a dietitian if vegan, vegetarian, or have food sensitivities
  • Keep quick snacks at nursing stations
  • Give yourself grace—a good enough diet is enough

❌ DON’T:

  • Start a restrictive diet to lose weight
  • Cut out food groups without medical advice
  • Skip meals—you need fuel!
  • Overdo herbal supplements without guidance
  • Compare your milk or diet to others
  • Ignore signs of dehydration (headaches, fatigue, dark urine)
  • Be afraid to ask for help

⚠️ Substances, Toxins & Breastmilk: What You Eat or Use Matters

While breastmilk is incredibly protective, some substances from your diet, environment, or lifestyle can pass into your milk. Let’s explore what’s safe, what’s not, and how to navigate tricky situations.

🍷 Alcohol

  • Alcohol enters your milk at the same concentration as your blood.
  • Wait about 2–3 hours per drink before nursing.
  • No need to “pump and dump” unless you’re uncomfortable.

✅ Rule of thumb: If you’re sober enough to drive, you’re likely safe to nurse.

💊 Medications & Herbs

  • Many medications are safe—but not all.
  • Always check with your provider or the LactMed database.
  • Be cautious with:
    • Some antidepressants, opioids, benzodiazepines
    • Cold meds or decongestants (may lower supply)
    • Herbal supplements like fenugreek, ginseng, and St. John’s Wort

🌿 “Natural” doesn’t always mean safe—ask before taking anything new.

🚬 Tobacco & Nicotine

  • Can lower supply and expose baby to harmful chemicals.
  • If you smoke:
    • Do it after feeding
    • Change clothes afterward
    • Consider switching to nicotine patches or gum
    • Get support—quitting is hard, but possible

🧪 Illicit Drugs

  • Substances like cocaine, heroin, meth, or ecstasy are not safe for breastfeeding.
  • These can quickly and severely harm your baby.

➡️ If you’re using or in recovery, speak to your provider—you can get help while safely feeding your baby.

🐟 Environmental Toxins

  • Avoid high-mercury fish (e.g., swordfish, king mackerel)
  • Use filtered water
  • Avoid BPA and plastic containers for warming milk
  • Choose fresh foods when possible
