If a man smokes and the woman they have child could that affect child?

Yes, smoking during pregnancy can have negative effects on the child. Smoking during pregnancy is associated with an increased risk of various health problems in children, including:

1. Low birth weight: Smoking during pregnancy can restrict blood flow to the uterus and placenta, leading to insufficient oxygen and nutrients reaching the fetus. This can result in low birth weight, which is associated with an increased risk of health problems in infancy and later life.

2. Preterm birth: Smoking during pregnancy increases the risk of preterm birth, which is defined as birth before 37 weeks of gestation. Preterm infants are more likely to experience health complications, such as respiratory problems, developmental delays, and long-term disabilities.

3. Sudden infant death syndrome (SIDS): Smoking during pregnancy and after birth is a significant risk factor for SIDS, the leading cause of death in infants between one month and one year of age.

4. Respiratory problems: Children exposed to secondhand smoke during pregnancy and after birth are more likely to develop respiratory problems, such as asthma, bronchitis, and pneumonia.

5. Ear infections: Children exposed to secondhand smoke are more likely to experience ear infections, which can lead to hearing problems.

6. Neurodevelopmental problems: Exposure to secondhand smoke during pregnancy and early childhood has been associated with an increased risk of neurodevelopmental problems, such as attention deficit hyperactivity disorder (ADHD), learning disabilities, and behavioral issues.

7. Increased risk of childhood cancers: Children exposed to secondhand smoke during pregnancy and early childhood are more likely to develop certain types of childhood cancers, including leukemia and lymphoma.

It is important for women who are pregnant or planning to become pregnant to avoid smoking and secondhand smoke exposure to protect their child's health.
