A study published in the journal Child Development found that two-year-olds whose mothers smoked regularly while they were pregnant were significantly more likely to exhibit an abnormal pattern of behavior over time compared to age-matched toddlers who were not exposed to cigarette smoke before birth.

While many toddlers exhibit mild behavioral problems during the “terrible twos,” the behavior problems of cigarette-exposed toddlers significantly increased between 18 and 24 months of age compared to the milder, more stable patterns of non-exposed toddlers.
