Tommy’s Midwife FAQs - Sleep Positions, Labour Signs & Baby Movements – Expert Advice for Parents

Discover answers by experts to common pregnancy questions

As the UK’s leading pregnancy research charity, Tommy’s team of expert and specialist midwives are on hand to provide support and advice to all expectant parents, before and during pregnancy. These experienced midwives have had extra training in specialist subjects, including pregnancy after loss; mental health; miscarriage and stillbirth.

We asked Tommy’s Midwife, Kate Marsh, to share her top tips on topics we know our community are keen to know more about.

1. What are the best sleep positions with a bump?

In the third trimester, the safest position to go to sleep in is on your side2. Reliable research has shown that going to sleep on your back in pregnancy increases your risk of stillbirth2 3.

You can go to sleep on either side as there isn’t enough evidence to show that sleeping on your left side is better than sleeping on your right side4.

Try putting pillows behind you to prevent turning on your back or using a pregnancy pillow between your knees and to support your bump.

2. What are the signs labour may be starting?

Common signs that labour may be starting include, having ‘a show,’ where the mucus plug comes away from your cervix, contractions (feelings of tightening in your womb, which may start off feeling like period cramps) and your waters breaking5. You may have backache and an urge to go to the toilet6. Braxton Hicks are when the womb contracts and releases. These are usually felt during the second or third trimester7 and are mostly uncomfortable but painless8. Contractions tend to build up, becoming longer and stronger as labour progresses9.

You should call your midwife or maternity unit immediately if your waters break, if you're having 3 or more contractions every 10 minutes10 or if you think you’re in labour before 37 weeks11

3. What size should my bump be?

In your second trimester you may notice a small baby bump appear.12 This is because your womb moves up and out of your pelvis13 so you become more noticeably pregnant or ‘start to show’.  If this is not your first pregnancy you may have started showing earlier. This is because the muscles in your womb and belly have been stretched from your last pregnancy.

In your third trimester your baby is continuing to grow in weight and size14. As your baby gets bigger, you’ll probably notice your bump expanding.

Towards the end of your pregnancy your baby's head moves down into the pelvis ("engaged"), and you might see your bump drop a bit15.

Remember, every pregnancy is different for everyone so try not to compare yourself.

What does baby movement feel like throughout pregnancy?

Most people become aware of their baby moving when they are 16-24 weeks pregnant.16This can be different depending on if this is your first pregnancy.17

You feel your baby’s movements as a kick, flutter, swish or roll18.  As your pregnancy progresses, you may feel kicks and jerky movements.19

As your baby grows you should feel them move more20, moving right up until and during labour 21.

There’s no set number of movements you should feel every day22. Get to know what is normal for your baby. If you notice that your baby’s movements have slowed down, changed or stopped, it may be a sign that your baby is not well23. Contact your maternity unit immediately.
