Can you sleep on your stomach while pregnant?

Yes, you can sleep on your stomach during pregnancy for as long as it feels comfortable. Tommy’s states that sleeping on your stomach is fine in early pregnancy, while the NHS says that as your bump grows you may find sleeping on your side more comfortable.

The guidance changes later in pregnancy, but not because stomach sleeping suddenly becomes dangerous. From 28 weeks, the NHS recommends going to sleep on your side rather than on your back because research has linked going to sleep on your back with a higher risk of stillbirth.

If you wake up in a different position, there is no need to panic. The NHS advises simply turning back onto your side before going to sleep again.

Is sleeping on your stomach safe in early pregnancy?

Tommy’s says it is fine to sleep on your stomach during the early stages of pregnancy.

For many people, the main issue eventually becomes comfort. Breast tenderness, bloating and a growing bump can make a previously familiar sleeping position less appealing, sometimes well before it becomes physically difficult.

You do not need to stop stomach sleeping at a particular early pregnancy week simply because you are pregnant. If the position feels comfortable and you have not been given different advice by your maternity team, current guidance does not tell you to avoid it in early pregnancy.

Can sleeping on your stomach squash the baby?

It is understandable to wonder whether lying on your front could put pressure on the pregnancy.

The pregnancy develops inside the uterus, and the baby is surrounded by amniotic fluid. Tommy’s specifically says that sleeping on your stomach in early pregnancy is fine.

As pregnancy progresses, your body may make the decision for you. A growing bump can make lying fully on your stomach uncomfortable or simply impractical.

If you feel pain, significant pressure or another symptom that worries you in any sleeping position, change position and discuss persistent or concerning symptoms with your midwife or maternity team.

When does stomach sleeping become uncomfortable?

There is no universal week when everyone has to stop sleeping on their stomach.

Bodies and bumps develop differently, and comfort can change gradually. Some people stop wanting to lie on their front quite early, while others remain comfortable for longer.

Rather than using a fixed deadline, pay attention to how the position feels. If you are repeatedly waking because your stomach, breasts, hips or back feel uncomfortable, experimenting with a side position and extra pillow support may help you settle.

Your sleep position does not need to look perfect. The aim is to follow the evidence-based guidance while finding a position you can realistically sleep in.

What is the recommended sleeping position later in pregnancy?

From 28 weeks, NHS guidance recommends going to sleep on your side, either left or right.

This recommendation is specifically about avoiding going to sleep on your back in later pregnancy. The NHS explains that research has linked going to sleep on your back after 28 weeks with a higher risk of stillbirth.

Tommy’s gives the same advice and says the safest position for going to sleep after 28 weeks is on your side.

Both sides are considered suitable. You do not have to sleep only on your left side unless a healthcare professional has given you individual advice to do so.

What if you wake up on your stomach or back?

People move during sleep, and waking in a different position can be unsettling if you have been trying hard to follow pregnancy sleep guidance.

The NHS specifically addresses this for back sleeping. If you wake on your back after 28 weeks, turn onto your side and go back to sleep.

Tommy’s also says not to worry if you wake on your back and advises rolling onto your side again.

You do not need to spend the night trying to monitor every movement your body makes. Focus on the position in which you settle to sleep, including when returning to sleep after waking during the night.

Can pillows make side sleeping more comfortable?

Pillows can be useful if side sleeping is unfamiliar or your changing body needs more support.

The NHS suggests trying a pillow to support your bump and putting another between your knees. You can use ordinary pillows rather than buying a specialist pregnancy pillow if they work for you.

Some people prefer a long body pillow or a shaped pregnancy pillow because it can support several areas at once. Others find several smaller pillows easier to move around.

There is no single pillow arrangement that everyone needs. Choose whatever helps you settle comfortably while following the recommended side-sleeping guidance later in pregnancy.

What if side sleeping is difficult?

Sleep can become more disrupted during pregnancy for many reasons, and changing your usual sleeping position can add another challenge.

If you normally sleep on your stomach, moving towards side sleeping gradually as your bump grows may feel more natural than trying to force a new position before you need it.

Pillow support may make the change easier. You could experiment with a pillow between your knees, one supporting your bump, or a pillow behind your back to make the position feel more stable.

If pain, breathlessness, restless legs, heartburn or another pregnancy symptom is repeatedly affecting your sleep, mention it to your midwife or GP. Persistent sleep problems can have different causes, and individual advice may be more useful than repeatedly adjusting your pillows.

Does the left side matter?

You may have heard that pregnant people must sleep on their left side, but current NHS guidance says you can go to sleep on either your left or right side.

Tommy’s also says that sleeping on either side is equally safe.

That gives you some freedom to change sides according to comfort. If one hip becomes sore or one position feels awkward, you can switch to the other side.

If your maternity team recommends a particular position because of your individual circumstances, follow their advice rather than general online guidance.

When to get professional advice

Speak to your midwife or GP if pain or another symptom is making it difficult to find any comfortable sleeping position, if poor sleep is having a significant effect on your daily life, or if you have been given individual pregnancy advice that makes you unsure which position is appropriate.

Sleep-position questions by themselves do not usually require urgent care, but symptoms that happen while you are resting should not automatically be blamed on your position.

Contact your maternity unit or NHS 111 if you develop pregnancy symptoms that concern you and you are unsure what to do. Follow your maternity team’s urgent advice for symptoms such as vaginal bleeding, reduced or changed fetal movements once you are at the stage when movements are normally monitored, severe pain, or signs that labour may be starting unexpectedly.

Call 999 for a life-threatening emergency, including severe difficulty breathing, loss of consciousness or another symptom requiring immediate emergency care.
