If you’re in the sweet spot of the second trimester and still not sleeping, hi friend—pull up a pillow. I remember thinking this would be the easier trimester, but my nights told a different story: I finally got comfy on my left side and—boom—baby dance party. I’d shuffle to the bathroom (again), then lie there wide awake while my brain replayed tomorrow’s to-do list and whether the nursery rug should be sage or sand. Been there.
Here’s the reassuring truth: second trimester sleep problems are really common. Hormones are still shifting, your belly is growing, the nasal passages can feel stuffy, and heartburn has opinions about bedtime. The good news? Small, realistic tweaks make a big difference—no elaborate routines, just mom-tested steps you can start tonight. Below, I’ll walk you through what’s going on, the most helpful fixes (with practical mini how-tos), a bite of expert insight, and clear signs it’s time to call your provider. By the end, you’ll have a gentle plan to get more rest—without turning sleep into another full-time job.

Why second-trimester sleep can be tricky (in plain mom speak)
- Position puzzles. Side sleeping is generally recommended as your bump grows—especially in mid/late pregnancy—to support blood flow. If you wake on your back, don’t panic; just roll to a side and get cozy again. Pillows help a ton.
- Heartburn & slow digestion. Progesterone relaxes the valve between your stomach and esophagus and the uterus crowds the stomach a bit—lying down can bring on the burn. Elevation and meal timing help.
- Nasal congestion (“pregnancy rhinitis”). Extra blood flow and hormone changes can swell nasal tissues—snoring, mouth breathing, midnight water breaks. Moisture and saline are your friends.
- Leg cramps / RLS. Restless legs and calf cramps can spike in pregnancy; iron status sometimes plays a role in RLS. Gentle stretching, warm baths, and a chat with your provider can help.
- Busy brain. Even when your body’s tired, your mind might be planning car seats at 1 a.m. (Relatable.)
10 practical, actually-doable fixes (pick two to try tonight)
You don’t need a perfect routine—small + steady wins. Add a new habit every few nights.
1) Build a cozy “side-sleep nest”
Why it helps : Side sleeping supports circulation for you and baby; pillows reduce hip and back aches.
How to do it : Lie on your side (left is often comfiest), tuck a pillow between knees, and slide a small pillow or folded towel under your belly for lift. A body pillow can wrap behind your back for anti-roll support. If you wake on your back, just roll—no guilt needed.
Mom note: I kept a small throw pillow in the sheet for quick middle-of-the-night shuffling.
2) Heartburn-proof your evenings
Why it helps : Gravity matters—elevating your upper body keeps acid where it belongs.
How to do it : Finish dinner 2–3 hours before bed, choose smaller portions, and avoid your personal triggers (spicy, fried, tomato-heavy). Sleep with your head and shoulders elevated on a wedge or extra pillows. Ask your provider about safe antacids if needed.
3) Tame the stuffy nose (hello, humidifier)
Why it helps : Moist air protects delicate nasal tissues, reduces mouth breathing, and can quiet snoring.
How to do it : Run a cool-mist humidifier nightly; add saline spray or rinses (use distilled or boiled-then-cooled water for neti) before bed. Elevating your head a bit also helps.
Mom note : I kept travel-size saline on my nightstand and in my diaper-bag-turned-pregnancy-bag.
4) Create a wind-down that your brain recognizes
Why it helps : Repeating simple cues trains your body to expect sleep.
How to do it : One hour before bed, dim lights and power down bright screens. Try a warm shower, light stretches, or a short guided relaxation. Keep it the same most nights. The NHS also recommends cutting evening caffeine and late naps.
5) Snack and sip…strategically
Why it helps : Blood sugar dips can wake you; too much fluid late sends you sprinting to the bathroom.
How to do it : Front-load fluids during the day; ease up after dinner. Try a light carb + protein snack before bed (crackers + cheese, yogurt + granola) to steady the night.
6) Stretch the kinks out (and calm restless legs)
Why it helps : Gentle movement reduces crampy calves and RLS discomfort so you settle faster.
How to do it : Before bed: ankle circles, calf stretches against a wall, and a slow hamstring stretch. If restless legs bug you often, ask your provider about checking iron levels; current sleep guidelines emphasize iron evaluation for RLS.
7) Move—earlier, not later
Why it helps : Daytime activity deepens sleep; late hard workouts can rev you up.
How to do it : Aim for light-to-moderate movement most days (walks, swimming, prenatal yoga) and keep intense exercise away from bedtime (with your provider’s OK). Even a 15-minute after-dinner stroll helps.
8) Make night bathroom trips…less disruptive
Why it helps: You’re going to pee (hello, growing uterus). The goal is quick out-and-back.
How to do it: Keep a small nightlight or motion-sensor light so you don’t fully wake after blinding yourself. Avoid checking your phone—blue light = brain party.
9) Manage the mental swirl
Why it helps : Worry is loud at 2 a.m. Clearing your mind helps your body follow.
How to do it : Keep a bedside notepad to “brain-dump” to-dos. Practice 4–6 breathing (inhale 4, exhale 6) for 3 minutes. If you’re wide awake after ~20 minutes, get up briefly—dim light, boring task—then try again.
10) Upgrade your sleep setup
Why it helps : Little physical tweaks pay off every single night.
How to do it : Cool the room a few degrees, use blackout curtains, and choose breathable cotton sheets. If your mattress is firm, a soft topper under your hips/shoulders can be magic.
Tailored tips for common second-trimester sleep complaints
Back & hip aches
- Body pillow between knees to align hips; small pillow under belly.
- Gentle cat-cow and pelvic tilts before bed.
- Consider a maternity support band during the day to reduce evening soreness.
Heartburn
- Earlier dinner, smaller portions, skip trigger foods.
- Elevate head/shoulders at night; sleep slightly reclined if needed.
- Ask your provider about safe antacids or H2-blockers if lifestyle changes aren’t enough.
Congestion & snoring
- Humidifier + saline before bed; gentle blow one nostril at a time.
- Elevate head a bit; sleep on your side with support.
- If you have loud, frequent snoring or gasping, mention it—sleep apnea can appear or worsen in pregnancy and deserves a check.
Leg cramps / Restless legs
- Hydrate through the day; stretch calves before bed.
- Warm bath or warm compress to calves.
- Ask about iron studies if RLS is frequent; iron repletion is often part of management when levels are low.
Wide-awake mind
- Keep bedtime low-stim and repeatable.
- Try 10 minutes of guided relaxation or prenatal meditation.
- Journal one “win” from the day and one thing you’re looking forward to tomorrow. It’s a gentle signal to your brain: we’re safe to rest now.
A simple “sleep better this week” plan (copy/paste)
- Day 1 — Nest setup: Add a pillow between knees and a small one under your belly; elevate your head slightly.
- Day 2 — Evening routine: Power down screens an hour before bed; warm shower + 5 minutes of stretches.
- Day 3 — Heartburn helper: Move dinner earlier, shrink portions, and sleep with a wedge/extra pillows.
- Day 4 — Humidify: Start a cool-mist humidifier and use saline before bed (distilled/boiled-cooled water if you neti).
- Day 5 — Move smart: 20–30-minute comfortable walk before sunset; gentle calf stretches at bedtime.
- Day 6 — Brain quiet: Keep a bedside notepad; try 4–6 breathing for 3 minutes if you wake at night.
- Day 7 — Review & adjust: Keep what worked; if snoring/gasping is loud, heartburn is severe, or RLS is frequent, message your provider for tailored help.
Expert insight (bite-size and mom-friendly)
- Side sleeping is recommended as pregnancy progresses. If you wake on your back, simply turn to a side—don’t stress. Pillows can make side sleeping more comfortable.
- Heartburn in pregnancy is common due to hormonal changes and slower digestion; smaller meals, avoiding triggers, and elevating your head can help—medications may be considered if lifestyle steps don’t cut it.
- Pregnancy rhinitis (stuffy nose) is real. Humidifiers and saline are first-line, drug-free helps; use distilled/boiled-cooled water for sinus rinses.
- Restless legs : current sleep guidelines emphasize checking iron and supplementing when needed; talk with your provider if RLS is stealing your sleep.
When to call your healthcare provider
Most sleep issues are normal and fixable, but reach out promptly if you have:
- Loud, frequent snoring with gasping or pauses in breathing (possible sleep apnea).
- Severe heartburn that doesn’t improve with lifestyle changes or safe meds.
- Restless legs or leg cramps that are frequent and disruptive (ask about iron testing).
- Persistent fatigue that affects daily life despite good sleep habits.
- Low mood or anxiety that makes falling or staying asleep difficult.
- Any symptom that simply feels off—you know your body best, and your team wants to help.
Wrapping Up with Love & Support
Mama, if sleep feels like a moving target, it’s not because you’re doing anything wrong—it’s because your body is doing so much right. You’re growing a baby, rerouting blood flow, balancing hormones, and making room in every sense. That’s a lot for one human at 3 a.m. So let’s release the idea of perfect nights. Two fewer wake-ups is a win. Ten extra minutes of deep sleep is a win. Swapping doom-scrolling for a warm shower and a book is a win.
Be gentle with yourself. Keep what helps, let go of what doesn’t, and call your provider when you need backup. You’re doing beautifully—even on the nights you can’t see it.
