Button Closures on Maternity Pants

Was it someone's idea of a cruel joke to put a button closure on a pair of maternity pants? I put on a pair yesterday that I had only worn 4 or 5 times and sure enough, the button popped off. This is not a good time in a woman's life (really no time is) to have your pants tell you that you're getting too big. Oh well. I do love the pants with the elastic that covers your entire belly. Now those are some good pants.
