Find out why many mums-to-be are still listening to pregnancy myths.

Mothers-to-be still mistakenly believe that tucking into a curry brings on labour, according to a recent poll.

Almost one in five (18%) women think wolfing down spicy food will help induce labour, while 38% believe raspberry leaf tea is the answer.

Old wives tales

Other "old wives' tales" frequently thought to be true include not being able to start exercising during pregnancy (39%) and that sleeping on your back can harm the unborn baby (25%).

The survey also found that 13% of women believe they are having a boy if they carry the baby "all at the front" while 7% think drinking coffee in pregnancy affects their baby's skin.

The poll, of more than 1,200 women, was carried out by the charity Tommy's and Johnson's Baby.

Tommy's midwife Sharon Broad said: "Eating curries or drinking raspberry leaf tea will not, unfortunately, induce labour.

"There is no evidence to support this. I still speak to many women, however, who continue to eat spicy food and take raspberry leaf tea in late pregnancy hoping that either will bring on labour.

"Carrying a baby boy with your pregnancy bump all at the front, damaging your baby's skin by drinking coffee or hurting your baby by sleeping on your back are also modern myths.

"It's true that in later pregnancy sleeping on your side, supported by pillows, will be more comfortable and help boost your blood circulation."

The survey found confusion over the types of food that are safe to eat in pregnancy.

* A total of 62% of women are unsure what types of cheese they can eat

* 56% do not know what kind of fish they can have and 50% are unsure about eating mayonnaise
* Almost half (47%) are confused over how much caffeine they can drink and 38% do not know how long they should take folic acid - which helps protect against spina bifida
* A third (33%) of women are confused about which sandwiches to choose, 30% are unsure how to cook their eggs and 31% are confused over the best sources of iron
* One in five (21%) women do not know if they can eat pate
* When it comes to exercise, 39% do not think they can start exercising if they were not active before the pregnancy, and 70% think women who have exercised before can carry on with knee bends and lunges

Ms Broad said: "This research continues to highlight the many different stories and myths on pregnancy.

"For example, pregnancy can be an excellent reason to start exercising.

"Although it's important to start off slowly, exercise will help your body to be in the best possible shape to cope with labour and giving birth.

"Deep lunges and knee bends would not be appropriate, neither would cycling in later pregnancy as your centre of gravity can change your sense of balance.

"A midwife or personal trainer could give you advice on different types of exercises you can do during pregnancy - even going for a walk is a start."

Penny says...

Model Penny Lancaster Stewart, who is supporting the Tommy's Let's Talk Baby information campaign, said: "I loved being pregnant - it's such an exciting time and I have found motherhood to be the most wonderful, life-changing experience.

"You want the best for your baby, and it's true that sometimes it's difficult to know what information is best to follow.

"There are so many stories and old wives' tales on pregnancy out there.

"I think it's great that with Tommy's you know that the information you're getting is coming straight from the professionals, and is an answer you can trust."
