Researchers who analyzed the role of nicotine among 63,128 mother-infant pairs in the Danish National Birth Cohort found that pregnant women who used nicotine replacement therapy to quit smoking were more likely to have babies with infantile colic. Smoking during pregnancy also was associated with a higher likelihood of colic. The findings are not a contraindication for the use of nicotine replacement as an aid to quit smoking during pregnancy, researchers said. The findings appeared in the journal Pediatrics.
