For you who live with 'the most important people in the world' (in IKEA's term) - children - especially the small ones, would probably very aware of how they 'rule' the house with their toys and other stuffs.
And you are probably still sitting on the fence when it comes to make decisions: What is the best arrangement for my kids' room? How can I make it? What do I need to put in there? etc..
Not to mention we who live in small space, have to do extra effort to fit all of our necessities AND for the children's as well.
But no worries, coz I've found a 'Children's Knowledge Book' here for your rescue ;)
