Pregnancy do's and don'ts

1. Smoking
Everything you take into your body in pregnancy is passed on to your baby via the placenta, including the toxins in cigarette smoke. Isn't it worth quitting or radically cutting down for your baby's sake?

2. 'Danger' foods
Steer clear of liver and liver pates, cook-chill foods, and unpasteurised, soft and blue-veined cheeses, since all these foods can contain listeria bacteria. Avoid undercooked meat, especially pork, as it may contain the toxoplasmosis organism. Undercooked eggs and poultry may contain salmonella bacteria, which will make you rather than your baby unwell, but this could have a knock-on effect on your baby.

3. Alcohol
There are no real trials or evidence as to how much, if any, alcohol is OK, so to be on the safe side, most professionals suggest avoiding it altogether when pregnant. However, the odd glass of wine after the first trimester is most unlikely to damage your baby.

4. Preventable problems
Ring your GP or midwife if you notice any usual symptoms - even if you don't think they're pregnancy-related. Very itchy skin, especially on the hands, can indicate a serious liver problem of pregnancy; nausea and vomiting in the later stages can be signs of pre-eclampsia, a treatable high blood pressure condition.

5. Missing antenatal appointments
You are legally entitled to paid time off for antenatal appointments, and it's important that you attend. Recent recommendations by the National Institute for Clinical Excellence (NICE) mean that women will now be offered fewer routine antenatal appointments (7-10 rather than 12-14). According to a spokesperson for the National Collaborating Centre for Women's and Children's Health, which supports the guideline, the emphasis is now "quality, not quantity".

6. Changing pet litter trays
Some pet faeces - particularly cats' - may contain a parasite that causes toxoplasmosis, an infection that can have devastating consequences for an unborn baby if contracted early in pregnancy. The risk of first-time infection in pregnancy is low, but to cut the risk still further, avoid changing pet litter trays and always wear gloves when gardening.

7. Hot baths
Stick to a warm soak, since very hot water can lower your blood pressure and make you feel sick or faint. Also it's not yet known what effect very hot water can have on bloodflow through the placenta, or if extremes of temperature could have an adverse effect on an unborn baby.

8. Stress
Medical research has proved that high stress levels in pregnancy can reduce the bloodflow through the placenta. In extreme circumstances, this can cause low birthweight or even prematurity. Studies also suggest that babies born to relaxed mothers tend to cry less, so it's worth trying to avoid situations that are likely to stress you out.

9. Hurting your back
As pregnancy progresses it's important to take care of your back. Try to maintain a neutral spine whether you're sitting or standing (keeping your feet shoulder-distance apart and relaxing your knees a little helps when standing). Avoid lifting heavy objects.

10. Eating peanuts
According to advice from the Department of Health, if you, your partner or any close family member has an atopic allergic condition such as eczema, asthma or hay fever, or a known peanut allergy, you should avoid peanuts and peanut products.
