It should be noted that the worst risks of smoking (lung related diseases and cancer due to smoke irritation) are not experienced by the unborn child as smoke is not coming into contact with it's airways.

Routine exposure to nicotine, a potent stimulant, is the problem. Being a potent stimulant, it can interfere with the endocrine system and thus can affect growth. Because children are growing so quickly, they are especially sensitive to hormone fluctuations. Stimulants simulate or stimulate the production of stress hormones like adrenaline and cortisol. Stress hormones are catabolic and counteract growth hormones, which are anabolic. As was previously said, routine stress can be almost as bad. Stress can be defined as anything that causes the fight/flight response to kick in and stimulate the release of adrenaline and cortisol.

Stress hormones are very useful in animals who must work hard for their food and to whom each calorie is precious. It ensures that as long as an animal is in danger, it will be using all available resources for the energy to run or fight or storing them as fat for near future use. None are spared for growth and prolonged stress hormone levels can actually reduce muscle tissue mass. As people, we no longer live under the same evolutionary pressures that formed our body responses, which is why the way our bodies do things somtimes seems strange.
