It is also important to pay attention to your diet. Many women feel they should 'eat for two', but research has shown that women only need an extra 200-300 calories a day while pregnant, and you may be eating those extra calories anyway. What is important is to ensure that you get the protein, vitamins and minerals necessary to build another human being. Those extra 200-300 calories should not be squandered on chocolate or crisps, but should be eaten as fruit, vegetables, etc. It is also important to increase your water intake, which will help avoid constipation.
Nobody knows how much alcohol it is safe to consume during pregnancy, so many health experts feel it is better to avoid alcohol entirely for the sake of the baby. This can seem hard on the pregnant woman when everyone else is drinking, but it is important to remember that alcohol is a poison for the growing baby, and no caring mother willingly gives her baby poison.
It is also important to minimize exposure to toxic chemicals while pregnant, so spending a lot of time painting the house and laying new carpets is not a good idea, especially in the early stages of pregnancy when the baby is particularly vulnerable.
Making a new life is something miraculous. Doing the best you can for that new life starts long before you have the baby in your arms for the first time.
