For something that is good. But it seems to work more with the "habits" that probably aren't so good. Like taking drinks to bed. I never let them do it as babies or toddlers. And I'm not sure on how it started but I think one of them was sick and wasn't drinking much. I let him have some watered juice when they went to bed. When he was better, I tried to tell him no more juice to bed but that was met with cries, lots of cries and I gave in. Then the other son saw was the first son was getting and demanded it for himself. Now years later...
Ryan recently switched to drinking from a thermos. He only has one so I have to wash it every night. So Ryan no longer takes his drink to bed. Yay! So I am working on getting Andy to relinquish his. The ironic thing is that Andy doesn't even drink the juice. Every morning he brings a full cup into the kitchen.
Sometimes Andy misplaces his cup and can't find it. I won't look for it especially close to bed time. Last night, he said he couldn't play his DS (because he didn't have his cup.) I told him he could but he was adamant. Tonight was the same thing and of course he gets upset. I am not sure why he feels the need to punish himself like that. But at the last minute, he found his cup and happily grabbed his DS.
I think I will try watering down his nighttime juice. Then I can work on him keeping his clothes on while at home.
