Hi Cgilker,
I know your problem,I have a 15 month old toddler. I have M22's on 24 inch stands,but I also have them wall mounted aswell.Which my son can not bang in to them by mistake and knock them off their stands because their wall mounted.I didn't want them just wall mounted because if he was playing on the floor under the speaker and went to stand up,he would hit his head on the bottom of the speaker and get hirt. So this would solve your problem,It did for me.
