Spinoff of the thread re: parents asking their kids for money.
Do you have a plan for retirement? Are you counting on social security or are you also saving money otherwise? Do you expect that your kid(s) will financially support you later in life (under regular circumstances, not talking about a serious unexpected hardship situation).
For us: We don't count on social security at all. Both DH and I started saving for our retirement with our first jobs out of college. Currently we just do 401ks/IRAs but as we get older/more financially secure we hope to invest some money beyond traditional retirement funds as well. We definitely do not expect our LO to ever give us money.
