Is it a problem for the developing baby if mother smoke but another member of household smokes?

Yes, it can be a problem for the developing baby even if the mother does not smoke but another member of the household does. Secondhand smoke, also known as environmental tobacco smoke (ETS), contains over 7,000 chemicals, many of which are known carcinogens. These chemicals can cross the placenta and reach the developing fetus, even if the mother herself is not smoking.

Exposure to secondhand smoke during pregnancy has been linked to a number of adverse outcomes for the baby, including:

* Low birth weight

* Premature birth

* Sudden infant death syndrome (SIDS)

* Increased risk of respiratory problems, such as asthma and bronchitis

* Increased risk of ear infections

* Increased risk of developmental problems, such as learning disabilities and attention deficit hyperactivity disorder (ADHD)

As a result of these risks, it is important for women who are pregnant or planning to become pregnant to avoid secondhand smoke as much as possible. This means avoiding places where smoking is allowed, such as bars and restaurants, and asking smokers to smoke outside. It is also important to talk to your healthcare provider about any concerns you may have about secondhand smoke and your pregnancy.
