Have you guys ever stop to think that with the way they age Elves could have A LOT of children?

I just realized this on a whim but, can you imagine how many children an Elf could have in all the time they are alive? The romantic life of an elf can have so many ups and downs really. Like, how come we don't hear more about this?? Specially with Half elves. They mature so fast in comparison to the Elf Parent! Like how cool could it be to make an Elf mother whose only goal in adventuring is to go visit their children? For an Elf going to visit them with 20 years of walking or something is absolutely nothing but more than an entire campaign can happen in this time.
