I'm trying to find a book I used to read when I was little.?

I vaguely remember it but what I do remember is that it's about dolls that are alive but can only move around when the humans are either gone or asleep. I'm about 95% sure it has a pink cover and it's pretty long. I've looked at google typing in "The Dollhouse" for a title but I'm not sure if that's the name. If there's anyone out there that knows what I'm talking about, please help me. I want to buy this book.
