A growing bump, bathroom trips and discomfort disrupt sleepEvidence-based & doctor-reviewed
Sleep trouble is very common, especially later on — a growing bump, frequent urination, heartburn, leg cramps, back pain and an active mind all interfere. Good sleep habits and side-sleeping with pillows help.
Why it happens
- A bigger bump makes it hard to get comfortable.
- Frequent urination at night.
- Heartburn, leg cramps and back pain.
- An active mind and anxiety.
Better sleep tips
- Sleep on your side (left is ideal) with a pillow between your knees and under the bump.
- Limit fluids close to bedtime.
- Keep a calming routine; cool, dark room.
- Treat heartburn with smaller evening meals.
When to see a doctor
Mention it if you have severe insomnia, loud snoring or gasping (possible sleep apnoea), or restless, crawling legs at night.
Frequently asked questions
What is the best sleep position?
Side-sleeping, ideally the left side, improves blood flow to your baby.
Why do I keep waking to urinate?
Hormones and the uterus pressing on the bladder increase nighttime urination.
Is it safe to sleep on my back?
From the second trimester, side-sleeping is advised; try not to settle flat on your back.
