Depending on whether she has frozen embryos "left over," it may not be as time-consuming or expensive to try for a sibling. As for raising two kids, in some ways, having a sibling to play with has eased my parenting demands and the costs (other than childcare) have not risen dramatically.
How old are your kids? Of course it is more expensive to raise more than child. A few costs I can think of (other than childcare): activities, camps, traveling, grocery bill, eating out, entertainment, school fees/supplies/tutoring, COLLEGE.
