How Many Children Is Too Many?

Im guessing 20

I would think that for 2 parents they should only have 5 children at the most

When you get to the point that you can not care for them properly, and that is giving them a quality life, with food, clothing, shelter and a proper education without feeling that your back is against the wall, because when you have problems they only trickle down to the children and ends up the entire family is miserable, if a child needs something and you can afford to give it, the child is sad and you are miserable, and it ends up a mess, so the parent should know when they can't aford a child or another child no one should have to tell a adult how many to have because some people should not have any because they don't even have parenting skills and don't try to get them.....    

Too many to me is like maybe 10 more...

There is not to many children that you can have to make you happy. But, when you pass 8 you are on the limit where you should stop and think about you own life and your families.
