Dreading the 'Terrible Twos'? Don't Smoke, Mothers Warned
Women who smoke during pregnancy are more likely to have toddlers who
display negative behaviors, such as impulsiveness, risky behavior, and
rebelliousness. These behaviors often persist into adulthood.
If a woman who smokes becomes pregnant, she should try to quit or at least
cut down on smoking to prevent these behavior problems as well as premature
birth and low birth weight.
Researchers are still unsure why smoking during pregnancy is associated
with negative behaviors.
