Difficult to respond to any stimulus baby emerging from the outside, looking at the time the baby woke from his sleep. Not only eye movements, other physical reactions seemed slow compared to babies whose mothers did not smoke cigarettes either actively or passively.

Chang's research conducted on 20 babies aged between 8 to 12 weeks showed that the nicotine contained in tobacco that causes disruption of the nervous system. Therefore, the process of stimulation by the baby's acceptance to the change in external conditions was slow.
