Sounds like he's trying to get your attention & then turning troublemaking into a game. What is he doing anyway? Are you being too strict?
If you aren't, pick the major issues that you absolutely feel that you must "discipline" & let all the little annoyances slide. Concentrate on positive itneractations & praising him for anything positive. Give him little bouts of as much positive 1 on 1 time as you can - 10 minutes mult. times a day. Continue to let the little things slide.
Now, if a major issue happens, use whatever consequence you've decided on (with his input when he's old enough) & STICK TO IT. If he laughs, that's ok as long as the consequence occurs. Pick a consequence that he'll care about (no toy, no TV, no special snack, etc). DO NOT call Daddy - he has to know that you're serious & that actions have immediate consequences.
Good luck & remember that 3 (almost) is still very little.
