Something from the "Number of kids and what people think" thread got me thinking. Am I correct in thinking the following:
1. Under normal circuмstances, a married couple should do nothing to avoid having children.
2. Under grave circuмstances, a married couple may, but is not obligated to, avoid having children by abstaining from the marital act. (NFP is for another discussion, please do not derail the thread.)
3. A married couple is never obligated to actively try to have more, or any, children, so long as the above are being followed.
Is this correct?
