Taking care of yourself during twin, triplet or more pregnancy starts with eating well – although there has been little research done on what that means for a mother carrying multiples.

In the absence of any real science, it’s probably best to aim for healthy, balanced meals along the lines the NHS promotes to all pregnant women. You will need to drink plenty of fluid, ideally eight large glasses of water a day as a minimum. It’s worth bearing in mind that sugary snacks can give you highs and lows which may be unpleasant and can also lead to developing diabetes in pregnancy. Slow-burning foods such as whole grain breads and crackers, vegetables, beans, oats, brown rice and whole grain pasta will tend to keep your blood sugar more stable and may satisfy you for longer.

You will need more protein, calcium, iron, folic acid and Vitamin B12 than in a singleton pregnancy, so make sure you have a varied diet. Try to eat little and often. Fresh foods are likely to give your body more of what it needs nutritionally than foods that have been processed. Taking a pregnancy supplement is also a good idea.

Boring but important, pelvic floor exercises do minimise the risk of a prolapsed uterus later in life, as well as help your pelvic floor return to normal after the babies are born. To do them, tighten the muscles around your vagina and anus (it feels like stopping the flow of urine) and count to five before relaxing the muscles. Do this ten times, repeating the whole routine five times a day. It can help if you put a discreet note somewhere where you’ll see it regularly or set a reminder on your phone reminding you to do a set. No one need know...

Gentle exercise during pregnancy can ease tension and help your muscle tone. Don’t do anything where balance is key as your centre of gravity will be changing as your belly grows. Low-impact sports like walking and swimming suit the majority of people. Whatever you choose, start slowly and stop if you feel any cramping, pain or shortness of breath.

Try to look after your emotional wellbeing as well as physical health. The extra hormones can sometimes make you feel emotional and overwhelmed. This is normal, even though it may surprise or upset you when it happens, especially if it isn’t how you usually react.

How big will I get?

Expectant mothers vary in size as in any pregnancy, but you can certainly expect to gain more weight than women carrying a singleton. In addition to the extra baby or babies, multiples mums carry extra placentas, amniotic fluid and maternal body fluid.

As the babies grow, keeping physically comfortable can be a challenge. It’s probably best not to plan a huge amount of activity for the last few weeks of pregnancy – getting in and out of cars as well as negotiating seatbelts can become difficult, and you will probably be more tired with all the extra work your body is doing. It can help to swap tips with other pregnant mums (as well as share experiences) via local clubs or call Twins Trust Twinline on 0800 138 0509. Our helpline is here to provide the support you need. Sometimes you may just need a listening ear from somebody that has been in your situation.
