It's strange to see a mother be depicted as the main character of a story - moreover it's even stranger for her to have two grown daughters. Usually the manga tries to have a cute appeal with babies and young children, but this just skips that. It's actually kind of refreshing. I am far from being a mother but I've always pictured it to be more like this, rather than simply have cute children to adorably love you. I mean I'm sure that's part of it, but most stories don't really make the children have personalities. I like this story very much.
