I spent way more on maternity clothes than I wanted to when I was pg with Jack. But on the plus side I didn't need anything extra the second time, although by the end things only just fit! I think that if you will get some wear out of it, go for it. Then you can use that to justify more kids LOL! But if you don't have more it doesn't matter, you can give it to a friend or family member, or sell them on EBay.
