Kudos to the First Years company for standing behind their product. Not surprisingly, my darling toddler and his razor-sharp new teeth managed to tear through one of their soft-spout sippy cups. I contacted the company to see if I could buy a replacement lid. They kindly send me an entire replacement cup. I was told "just this once" but still, that's wonderful. It was a favorite cup and now it can live on. For now. Anyway, thanks First Years!
