This is one of the main concerns of many women with asthma. Like other allergic conditions, such as hay fever and eczema, asthma often runs in the family.
Researchers are trying to show which factors in the environment also play a part. Some, but not all, studies have shown that breast-feeding in the first few months of life may reduce the chance of your baby developing allergic conditions, including asthma.
Mothers who smoke during pregnancy are more likely to have children that develop asthma and wheezing in their early years. The most important thing you can do to reduce a baby’s chance of asthma is to avoid cigarette smoke.
Your asthma medicines won’t harm your baby – in fact, your baby will do best if your asthma is under control, so it is important to continue with your asthma medicine. If you are concerned about your asthma, speak to your doctor, nurse or midwife.
You should have your asthma reviewed by your doctor or asthma nurse if you are pregnant.
