We started at 21, and we're 25 now? Any younger and we would have been teenage parents. Our friend couples are similar ages, so age is not a factor for us at least. At one point, a doctor suggested that my sperm could by a contributory factor as men's sperm doesn't fully mature until age 25. Honestly, doctors are better at helping older women, than younger ones.
One of the couples I know, the woman had her first miscarriage at 16. Believe it or not, young people can lose babies too....
Statistically he is correct. The "good" part it is common to have a miscarriage and then multiple healthy children. Unfortunately people do not talk enough about miscarriage and many hide them, creating impression that it is not a common thing.
One or two miscarriages is fairly typical. Three is about 1% of couples. We've had six miscarriages altogether along with the stillbirth, which is not common. Six puts you in the 1% of the 1%, which is the 0.01% and the stillbirth puts you in the 0.2% of that which is 0.002%.
Also, no matter how you slice or dice it, my friend's five full-term stillbirths are not common, and his perception that it's not common is not due to people not talking about it. Statistically, his experience is one in a million, and there is no slicing or dicing it. Saying it's common dismisses the very real condition that's causing their stillbirths.
Moreover, we've been to three specialists, and we've explained the circumstances of our stillbirth (baby's heart stopped overnight). All three have told us this is quite rare, and the most common presentation is slow fetal demise preceded by obvious growth delay. Ultimately, not all miscarriage is created equal, and the lack of distinction between different types is probably one of the things holding back research in this area. This isn't just my thinking several research papers have been published recently which make the exact same point.
I'm not denying the importance of not waiting til you're 40 to try. However, his comment that the children of young parents do not die is not true.
