Interesting way to describe the problem. However I think you are overlaying a couple of aspects here. I don't think age is the key factor in addictive or obsessive behaviors. My current thinking is that most people tend to behave like addicts. Some of the addictions are much more harmful, such as gambling, or even include physical aspects, such as alcohol. There is a dimension of "ease of addiction" in that some people are more likely to become addicted or behave obsessively, but my theory is that the easily addicted people are unlikely to stop completely, though they may be able to control their triggers. "Pick your poison" doesn't exactly sound like a solution.
However the child addiction aspect is really a problem with modern parenting in that the demands on parents have become too unreasonable. Raising kids is a full-time job, especially in the first few years, but our economic system, such as it is in places like America, don't really allow for that. Maternity leave could help a lot if it was universal and extended for several years without penalizing the women's careers. But replacement level calls for at least two children each, and that's a major problem as our economic system sees things. Extremely short-term, not sustainable "thinking". Kids are too vulnerable and need to be protected with a LOT of parenting. Subsidized daycare is usually a minimized and therefore too often a miserable solution approach. "Give 'em a computer" is becoming the worst of all possible solutions to childcare.
Going too high now, but... We have a fundamental problem with how our low-level programs conflict with our high-level programs. I think that most of that problem goes back to how evolution works in blindly developing those low-level programs. Quite easy to produce children and we are strongly motivated to try to do so, but human children are incredibly dependent and therefore we are also programmed at a low level to love them a lot. But Ma Nature works on a geologic time scale, and exponential growth is not allowed, while the genes are shuffled at random... So Ma Nature has a natural solution we can't stomach happily: More than four children but only two are allowed to live long enough to reproduce. Until quite recently we he had no way to see or assess how the genetic shuffling is going, so we had to love all of the kids equally and be extremely sad about the deaths of the ones with less lucky shuffles...
