It's a puzzling question.
At least to me.
Mya never seemed to have a problem. I don't know if that is a first-born thing or a girl thing, probably a first-born thing.
Getting the boys to pick up their toys is like pulling teeth (not the loose ones, the permanent adult ones). It's a frustrating chore. Many times I'm tempted to just do it myself, but where would the lesson be in that.
I've helped them pick up toys (and ended up finishing the job myself) I've tried asking nicely. I've tried asking multiple times in a short period of time. I've even tried asking in a very loud voice.
I've threatened them with punishments. I've told them they can't leave their room until its picked up (they were in their room for 3 hours).
Last week I came up with a new scheme.
I asked them to pick up. When they didn't listen, I picked up the toys myself and then I took them away in a box and hid them...
for a week.
And, for a week their room was relatively picked up (mainly due to the fact that their toys were being held hostage in the utility room).
But today, their room is again a disaster area.
Which I asked them to pick up...
And they have not.
In fact, I hear water running in the bathroom as I write this.
Not a good sign my friends, not a good sign.
And so I will head up stairs, pull out a box and start packing the toys away, again.
Here's hoping round two is a little more successful.
I'm not holding my breath. :)
