I agree with you that having a large family means increasing the population of the country. The worst that may happen is if the parents are not well to do, or are just managing to survive.

Another negative effects of the large family means losing of a job for the mother to take care of the kids. When I had my first child, I left the job since the baby needed more attention and it wasn't a government job. So, I managed to return the second time and I knew the stress I went through being jobless with two kids. I was able to go back to work and I am not ready to inconvenience myself that much for having more children.

I don't have reason for a big family, my country's economy is what no one would want to talk about, in that case, wisdom is profitable.

I enjoy reading every bid of the post, best wishes in the contest.
