The Duggars -- They're Freakin' Everywhere (TMZ TV)

Michelle Duggar's spent 135 months knocked up -- hence the 19 kids ... some of whom are now squeezing out their own broods! Yes, Jill just spent 70 hours in labor, even though she could have had the baby much sooner.

Why opt for that kinda pain? The answer involves -- you guessed it ... MORE KIDS!! Seriously, this family's spreading faster than the blob.
