Am i too keen, maternity?

I know its kind of crazy to buy before you get prego but unfortunately I fell victim to it this week. I found deals ($5.99 at Pumpkin Patch-the store personnel told me they are discontinuing their maternity line) that I couldn't resist. I did however buy only shirts in XS or small & honestly they could p for cute flowy/comfy shirts (they really aren't that much bigger then regular shirts). Its crazy but I did it as bad as it might be.....
