having a big family

Having a big family is great and it does have its ups and downs..who doesn't right?! So when i saw The Duggars and that they lost baby #20 i was a little upset. I think (and with Michelle being what she is-a god fearing human being) she knew what she was doing when she decided to get pregnant again. This is just my own personal thought and if anyone has anything to say about this, thats fine! they lost their unborn child to God knows what. I figured that the Lord was telling her something when their 19 child was born the way it was. Maybe im wrong and i hope to god i am but shouldn't she have known to stop when the last child was born prematurally that she should stop having kids. because number one yes HE says to multiply but not to the extent of hurting yourself?? does anyone aggre with me or am i alone?? I have a big family many sis and bro but i only have 2 girls and id like to keep it that way! i dont think i am cut out to be a mamma of more than that but if it happens it happens!
