I think you are right in not having children without really wanting them. In this situation you must put your and your husband's desires ahead of your respective parents. You may have to sit down with each set of parents separately and perhaps explain your point of view, and the folly of having children for them. Be gentle but firm and remind them that you are only 33 and may change your mind someday. But that having kids without wanting them will be bad for everyone involved- particularly the child.
