How would you discipline a 4-year old for drawing on walls or carpet with a black crayon? We have washed it off, mostly, but the walls and carpet still look grubby. If he were 2, I would blame myself for having let him get hold of the crayons unsupervised but he is 4 and we have told him numerous times that crayons are only used on coloring books or paper. We had taken his crayons away for previous behavior like this but today an older child gave them to him and we didn't notice until the damage was done (he did a lot in 10 minutes!).
My DH did something similar when he was DS's age and he said his parents smacked him and sent him to bed with no supper and took away some toys. That's excessive (obviously the smacking is not even on the table) I think but equally my DH said that at least he learned his lesson and never did something like that again.
I feel like discipline never gets through to my DS. I try to give natural consequences e.g. 'we're so tired from cleaning up this mess you made with the crayons, we can't read you bedtime stories tonight' or taking away the toys / crayons in question but it doesn't seem to have much impact. Is this just 4-year olds testing boundaries or should he really know better by now?
