As an Indian, this much I can say that two children(son and a daughter) is the best combination for an ideal couple though it depends on the financial condition of the couple.
I think in the current generation 2 kids are better for an ideal couple. Last depends on your choice how many kids are want and how to care in a proper way.
yes if circumstance allow, I encourage having one parent at home...kids are definitely my future...I will need somebody to take care of me when I'm super old
It depends on your financial situation. However even if you are very rich, one day is 24 hrs for rich people as well, and you can't spend enough time for each child if you have too many. 1-2 children is ideal. zero or three children is also okay if 1-2 children is not possible. More than 3 children is not good at all. Because you can't have enough time for more than 3 children. It's like site content. Go for quality rather than quantity.
As many as your pocket, house and body allows. and You can make sure that you can personally take care of your kids.
