Can the be too narrow for l delivery?

lol thats y they call it "the Miracle of birth" girl somehow it does stretch with out tearing or being cut. most likely it does tear but i understand there is different levels of tearing..level 1,2,3,4 and of course 4 is what u never want to experience. yes u can be too small to lly deliver but that only depends on the size of the baby and not really your . the is made to stretch honey.
