How many is to many??

So the Duggars just announced that they are expecting baby number 20. You would think after all the issues they had with #19 they might think about calling it quits. You would also think that maybe people should give others a tv show just because they can make a lot of kids. But really who is to say how many is to many?
We obviously have 3 kids and I have friends who tell me all the time they would NEVER want to have 3 kids. And I know people with 3 kids who say they would never want 4 kids.
I agree that 2 kids is a good number. I agree because you are not outnumbered. But I also love having 3 kids. Even if it does mean one of us has to take 2 kids when we are out it still works for us. As many know I would of had 4 kids if I could of, but that defiantly would have been enough for me. I get that people love kids. I get that we all love to hold our newborn babies and watch our kids reach their milestones. And we all daydream about the day they become doctors, or professional football players. But what people don't think about is the cost of kids.
Sure the Duggars home school ( NO THANK YOU!!!) so I guess they save some money there. And clearly no one is planning on going to college (good luck in the future) so theres so more money to save. But is that worth it?
When do people stop and think about what it really costs to have kids. As a mom of 3 I have learned ways to cut costs over the course of motherhood, but I haven't figured out how to make having and raising kids free. (if you have please tell me) And by free I don't mean welfare. I mean still being able to have the house we want, the lifestyle we have, the nice cars etc....and raise our kids without it costing anything. My guess...no one will ever figure out how to do that...because its NOT POSSIBLE.
I don't want to judge people I do not know but when you put your life in front of a camera and on tv you are inviting people in to judge you. I am sure they are nice people but I really think they are being idiots by having so many kids. I really think those kids are hurt by having so many siblings. I have 3 kids and it is hard enough finding a lot of one on one time with the kids. I can only imagine have 20!!!
But hey if you know someone who wants to give me a show about raising my 3 crazies let me know...Ill be happy to let people judge me!
