It is a big conundrum. There is a massive population bomb in Pakistan already and on the other hand if you don't have children then who will look after the old and work to sustain the country.
You can have kids but try to limit till two. That way everyone will still have kids and they will not become burden on country's resources in future.
Problem is when people loose their minds and keep making babies. It is stupidity to have 5-10 kids. Have mercy on your women too. Pregnancies destroy health of women too.
