Question
We have a three-month-old baby at home. Our elders hold the baby after drinking beer every day. Is this harmful to the baby?
Answer
Alcohol molecules (with a molecular weight of about 46) are larger than air molecules (with a molecular weight of about 29) and are easily volatile in the air. Therefore, the alcohol vapor emitted from a person’s body will disperse into the surrounding air. If the elders hold the baby for a short period of time and the baby can adapt, there is no need to be overly concerned about the impact of the elders’ drinking on the baby.
