If mothers and babies are healthy then all humanity is healthy, that’s why they are always studied by scientists, researchers and doctors. Previous studies have shown that babies exposed to tobacco in utero are more likely to have a low birth weight and are at increased risk for sudden infant death syndrome. But a recent research showed that these babies are also less likely to self-soothe and are more awaked and excitable than newborns whose mothers did not smoke during pregnancy.

In our days researchers from The Miriam Hospital’s Centers for Behavioral and Preventive Medicine said that early identification and targeted intervention efforts aimed at both infants and parents may prevent possible disruption in early maternal-infant bonding and long-term adverse outcomes. For to save the mother-child relationship, researchers said that is need for a better treatment programs for to help women not to smoke during pregnancy and to keep them from starting smoking after the baby is born, and to help them take care of an excitable or colicky baby.

According to a study between 11 and 30 percent of women continue to smoke during pregnancy. Tobacco exposure in utero has also been linked to long-term adverse neurobehavior outcomes in children, including conduct disorder and hyperactivity. Scientists studied newborns between 10 and 27 days old. At the end of this study they found from all 56 babies – 28 smoking-exposed and 28 unexposed – were healthy and full-term.

Mothers in the study were assigned to the smoking or non-smoking group based on self-reports of cigarette use during pregnancy assessed shortly after babies were born. Researchers measured cotinine, the primary metabolite of nicotine, in the mother’s saliva. Cotinine is readily passed from mother to infant, with the baby absorbing nearly as much as the mother does. Researchers found also that these mothers smoked from about 15 cigarettes per day in the first trimester and to approximately five cigarettes in the third trimester.
