The best advice I could give you would be to put everything that could be harmful to him in a locked container until he can be trusted...I had a son who was like this, constantly into everything, and felt such relief when I knew that all of the household products and medications were out of his reach! He may be bored, so you might try to engage him in an activity when you are trying to get housework done- my 2-3 year old loved to help me do laundry -he put it in the washer for me which was a challenge to him, because he wasn't tall enough to see if it went in so I made it a game. Also, with the laundry detergent, I think sometimes that little ones like to see what happens with different items. It may be worth the time and effort (cleaning wise) to set him up with finger paints, edible play-doh, etc. so he has a chance to use his senses in a safe way. Hope this helps!
