You’re Not “Too Young” for Perimenopause: Why Moms in Their Late 30s Need to Start Preparing Now

If you’re a mom in your 30’s or early 40’s with young children, chances are your days are already full. Between the snacks, school runs, after school activities, and interrupted sleep, there is very little time left for yourself. So when your energy dips, sleep gets weird, or your moods feel unpredictable, it’s easy to blame stress, work, your partner, or burnout.

Remember: You’re Raising Little Humans—But Your Hormones Are Changing Too

But here’s something many women aren’t told or isn’t considered: perimenopause often begins in your late 30s or early 40s—sometimes years before periods become irregular or hot flashes begin.

Understanding what’s happening early, and making some shifts in diet and lifestyle before symptoms ramp up, can make a huge difference in how you feel over the next decade.

What Is Perimenopause (and Why It Starts Earlier Than You Think)?

Perimenopause is the transition phase (often a decade) leading up to the end of your menstrual cycle. During this time, estrogen and progesterone don’t decline, necessarily—they fluctuate. I’m a menopause-focused nutritionist and a woman in post-menopause. My perimenopause decade felt like the storm before the calm.

This hormonal “roller coaster” can start 8–10 years before menopause, even if:

• Your periods are still regular
• You’re still having babies or chasing toddlers
• You feel “too young” for this stage

For moms with young kids, these changes often overlap with high stress, broken sleep, and nutrient depletion from pregnancy and breastfeeding—making symptoms easier to miss or mislabel.

Early Perimenopause Signs Moms Often Overlook

Perimenopause doesn’t always announce itself with a lab test or hot flashes. Early signs often look like “normal life stuff,” especially when you’re parenting young kids. In fact, there is not a perimenopause test you can ask your Doctor for.

Common early perimenopause symptoms can include:

• Trouble sleeping (especially waking between 2–4am)
• Increased anxiety or irritability (the sound of chewing makes you want to snap)
• Heavier or shorter cycles (you might skip a month or get your period twice in a month)
• PMS that feels more intense than it used to
• Brain fog or forgetfulness
• Feeling wired but tired (the story of all moms, especially with young kids)
• Weight gain around the middle despite no big changes (body composition and fat deposition changes in perimenopause and beyond)

These aren’t signs you’re failing—they’re signals your hormones are shifting. Hello, perimenopause!

Why Preparing Early Matters (Especially for Moms)

Most women tend to brush symptoms under the rug. But waiting until symptoms are severe often means playing catch-up, especially if the weight around the mid section.

Starting early helps:

• Stabilize blood sugar, which supports mood, sleep, weight, and energy
• Protect bone and muscle mass before estrogen drops further
• Support your nervous system, already taxed by motherhood
• Reduce the intensity of future symptoms, rather than reacting to them

Think of this strategy like laying a foundation—small changes now can mean less severe symptoms later in full blown menopause.

5 Foundational Practices to Start Before Symptoms Are Here For Good

These strategies are not extreme, expensive, or time-consuming. Despite what many women think about menopause or weight gain, you don’t have to exercise harder or eat less. These practices are healthy, sustainable, and realistic for moms.

1. Eat to Support Blood Sugar

Skipping meals or living on coffee and your kid’s leftovers stresses hormones and can cause your body to store food you eat as body fat.

Aim for:

• 20-30g minimum of protein at every meal, 3 times a day
• Healthy fats (olive oil, nuts, seeds, avocado)
• Non-starchy carbs paired with protein (not alone)

Stable blood sugar = fewer mood swings, better sleep, and steadier energy. This combination of macronutrients is easy to understand in my Balanced Food Framework. Use it to build every meal for better energy, sleep, and hormones.

2. Prioritize Sleep (Even If It’s Imperfect)

Sleep becomes more fragile in perimenopause and the years after. I get it, as moms we don’t sleep well…or we sleep with one eye open. But the truth is, without quality sleep, our digestion, food choices, energy, brain function, and hormones get thrown off.

Start now by:

• Eating enough during the day divided between 3 meals. Plus, make sure your dinner has protein because a carb-heavy dinner can cause mid night wake ups due to low blood sugar
• Avoiding caffeine late afternoon
• Creating a consistent evening routine—even 10 minutes counts where you shut everything off, drink herbal tea, make your room dark, and read before sleep

You’re not “bad at sleeping.” Your hormones just need some extra support. If there is light or stimulants like screens, alcohol, or sugar before bed, you will have trouble producing melatonin to fall asleep.

3. Reduce Synthetic Hormone Disruptors Where You Can

You don’t need to live perfectly and replace all your favourite cosmetics—but awareness matters.

Small shifts:

• Avoid heating food in plastic
• Choose products free from fragrance, dyes, parabens, and sulfates, when possible
• Ventilate your home by opening windows every day, especially when cleaning or cooking

This reduces the overall toxic “load” your liver has to process.

4. Build Muscle (Not Just “Exercise”)

Muscle is often overlooked, but so protective during perimenopause—it helps with:

• Blood sugar control
• Metabolism
• Bone density and strength
• Recovery and resilience

Try short strength sessions using hand weights, body weight, a weighted vest, or resistance bands 2–3 times per week.

5. Embrace and Welcome This New Phase

Here’s the truth: What worked at 28 may not work at 38. Don’t try to make it happen, just adjust and go with the flow.

Perimenopause is a phase of adjustment, not decline. Paying attention now helps you respond with curiosity instead of frustration later. Get to know how carbs are becoming more difficult to digest. Are they getting stored around your mid section? Does what you eat for dinner affect your sleep now, even though you could eat anything a few years ago? Do hard core spin classes cause your body more stress? If so, perhaps it’s time to slow down and tweak your fitness and nutrition routine to work for your hormones, not against them.

A Final Word for Moms

If you’re raising small children while entering this phase, you’re not behind—you’re right on time.

Preparing for perimenopause isn’t about fixing something that’s “wrong.”

It’s about supporting your body through change—so you can show up with more patience, energy, and confidence for yourself and your family.

This season is demanding. You deserve tools that make it easier—not harder.
