Nutrition by Trimester: What to Eat When Trying, Pregnancy & Postpartum

Whether you're preparing for pregnancy, growing a baby, or cradling your sweet newborn, your body is doing extraordinary work. Food becomes more than fuel—it's support, healing, and nourishment for both of you. Let's walk through what your body needs at each stage: preparing to conceive, navigating each trimester, and those early days postpartum. 

When You’re Trying to Conceive

Before the positive test, you’re building a foundation. According to Baylor Scott & White Health, a diet high in unsaturated fats, whole grains, legumes, fruits and veggies, varied proteins, and full‑fat dairy may improve fertility.

What to prioritize:

• Unsaturated fats: avocado, olives, nuts & seeds

• Whole grains & legumes: quinoa, chickpeas, oats

• Colorful fruits + veggies: variety matters

• Iron + folate (folic acid): leafy greens, lentils, beans — these nutrients help boost fertility

First Trimester

As your baby grows in the first trimester, you may experience energy shifts, nausea, and an unpredictable appetite. Keep your nutrition plan simple by sticking to the basics. 

 Focus on:

• Folate/folic acid: Helps prevent neural tube defects. Good sources: fortified cereal, spinach, lentils, according to the Mayo Clinic

• Iron: Your blood volume is increasing; you’ll need more to support both you and baby.

• Protein: Aim for quality sources like lean meat, poultry, fish (if cleared), eggs, beans.

• Hydration + gentle carbs: especially if nausea or low appetite show up.

Tip: Our Gluten-Free Ginger Prenatal Cookies have real ginger to help ease nausea, plus omega-3s, iron, calcium, zinc, and folate to support mama and baby’s health.

Second Trimester

Many mamas describe this as the “breezier” trimester, but baby growth is in full swing. The Mayo Clinic says core nutrients continue to matter, and your energy may start returning.

 Go heavier on:

• Omega‑3s: Fatty fish (if your doctor says yes), chia seeds, walnuts — supporting baby's brain and eye development

• Calcium & Vitamin D: Milk or fortified non‑dairy, kale, and broccoli

• Fiber + fluids: As metabolism slows a little, digestion support helps

• Protein and nutrient-rich foods: keep these steady

Tip: Listen to your hunger cues. Some days you’ll feel crampier or more tired — your body is working for two! 

Third Trimester

Your baby is almost here! Nutrients and appetite tend to ramp up; this is your time to stock your pantry and prep for the tiny human’s arrival.

Priority nutrients:

• Magnesium and potassium: Think sweet potatoes, bananas, beans — bonus for leg‑cramp relief.

• Iron boost: Your stores matter for delivery and recovery

• Healthy carbs: Whole‑grain pasta, brown rice, quinoa — fuel for growing, moving, preparing

• Quality protein: Keep it consistent

Tip: Now’s a great moment to prep easy‑to‑reach meals for after baby arrives — whether it’s batching soups or freezing something you love.

Fourth Trimester 

You did it, mama! This phase deserves equal care: whether you’re recovering, nursing, or just trying to find your new rhythm. Food is your ally.

What to eat:

• High‑quality protein: Helps heal and rebuild

• Veggies + whole grains: Support your energy levels

• Healthy fats: Omega‑3s, avocados, nuts — still essential

• Hydration: especially if nursing

• Specific nutrient check‑ins: Iron, folate, Vitamin D — the earlier pregnancy resources remind us these don’t just matter during pregnancy

• Miracle Milkookies: To give you a nutritious boost while you are breastfeeding! 

Tip: Be kind to yourself. Recovering is not a race. 

Final Encouragement

Your journey is uniquely yours, and your body is doing incredible things. The foods you choose matter—but they should bring you joy, not stress. Choose nourishment that tastes good, feels good, and supports you through this transformation. And if some days that means savoring a cookie because you absolutely deserve it? That counts too.

Here's to fueling you and your little one through every stage.
