Common myths about pregnancy

4-minute read

If you are pregnant, you might be getting a lot of advice from well-meaning people. You might be asking whether what they say is true. This article looks at some of the common myths you might hear and provides some answers.

Myth: Eating peanuts and dairy can make your baby allergic to them

Truth: It's perfectly safe to eat these foods unless you yourself are allergic to them, or if your doctor advises you not to.

There are some foods that it's best to avoid during pregnancy due to the risks in certain harmful microbes. They include some soft cheeses, patés, raw meat or fish, raw or partly cooked eggs, and soft-serve ice cream.

Myth: There are ways you can tell if it's a boy or a girl

Truth: The position of the baby in your tummy, holding a wedding ring over your abdomen and watching in which direction it turns, or how active the baby is are all ways you may had heard to tell if you are having a boy or a girl, but none of these methods works. In many cases, an ultrasound scan can reveal the sex of your baby. It isn't 100% reliable, but you can ask the ultrasound technician to tell you what they can see. You can also ask them not to tell you if you want to wait until the birth to find out.

Myth: I should be 'eating for two' while I'm pregnant

Truth: There is no evidence to show that you need to eat for two when you're pregnant. Overeating is bad for both you and your baby. Eating a healthy, balanced diet is what's important.

Myth: I shouldn't have hot baths, dye my hair or exercise while pregnant

Truth: It's perfectly safe to have a warm bath when pregnant, but avoid becoming too hot. During pregnancy, hormonal changes might make you feel warmer than normal.

The low level of chemicals found in hair dye is generally thought to be safe. However, many women still prefer to avoid dyeing their hair in the first 12 weeks of pregnancy.

Most exercises that you did before pregnancy will be safe, but check with your doctor or midwife. You might find you become breathless or feel hot more quickly during pregnancy. As a general rule, a light to moderate level should allow you to hold a conversation as you exercise when pregnant. If you become breathless as you talk, you're probably exercising too strenuously.

Myth: Morning sickness only happens in the morning

Truth: Nausea (and/or vomiting) during pregnancy can occur at any time of day, due to changes in your hormones. For most women, it's more common in the morning and begins to improve after 3 months. But for some women, it's different.

Myth: I can't have a cat in the house when I'm pregnant

Truth: There is no need to give away your pets when you become pregnant. A disease called toxoplasmosis can be harmful to your unborn baby — you can become infected by handling cat's faeces. Ask someone else to change your cat's litter, or wear gloves to do this — as well as when gardening — while you are pregnant.

Myth: Cream can help avoid stretch marks

Truth: There is no evidence that creams or oils can remove or prevent stretch marks, which often fade in time.

Myth: My heartburn means my baby has lots of hair

Truth: One small research study showed there might be a connection between having heartburn in pregnancy and the thickness of your baby's hair. However, heartburn is quite common in pregnancy.

Myth: It's unsafe to hang washing on the line

Truth: Reaching up above your head and hanging washing on the line is safe. It is unlikely that it will affect your baby's umbilical cord in any way. Your midwife or doctor will advise you if there are any activities that are unsafe for you in pregnancy.

Myth: I need to prepare my nipples for breastfeeding

Truth: There is no evidence that you need to prepare or tough your nipples before birth.
