Having a very high number of
children, two
children can be very expensive to raise in today's world/economy, but some people have more than 4. This wasn't a big deal in the baby
boom post WWII, when we had a population decrease. But in today's economy, and with our overpopulation, it's a really bad move, unless said person is Richie Rich/Daddy Warbucks. Most parents of these
baby trains don't exactly look the part of someone who can offer these
children a very good quality of life (at least, not THAT many kids..)
The term "Baby Train" refers to the appearance of the parents walking down the street followed in a single-file line up by several kids (or following behind several kids), giving the appearance of a train towing cars. If they're pregnant while having a ton of kids, it is sometimes referred to as the "caboose" for being the last
one (in theory) in the line up of "train cars".
It is questionable if these people are ever NOT pregnant, like half the kids were conceived in the delivery room or something. Also theorized that some
children are "expendable" in case poor parenting or a freak accident results in the loss of one, they would have a replacement, so to speak.
