I repeatedly see this 4:1 adult kind of message in your threads. I understand that your son is the only child living in your home which is full of adults (the 4 of you). But I don't think it is a problem. Unless you expect your child to behave like an adult, he can perfectly manage there. My kids play around the house, and the house get messy after each play session. But we let them be kids for sometimes. Throwing things, drawing in the wall, spreading the toys everywhere is all part of childhood, and age appropriate for them. However, re-arranging the house after each session would be frustrating. Not easy for the care-taker (grand mom) or the working mom (me). Kids' won't understand our sermons on this either. After several attempts to make them clean their mess, I've finally found a good way. That is the clean up song from their favorite cartoon Barney&friends. http://www.youtube.com/watch?v=PJhXVg2QisM Initially we were singing this song and enjoying the cleaning works together. Nowadays, we just play this song from the mobile. Kids will automatically clean up the place. They've learnt to clean, and also the importance of keeping the place neat. Since the message is child friendly, it has reached them so quickly and positively.
