toddler "issues"

Hi all, To piggyback on Ed Dad's thread (Dora, D-D-Dora, swiper no swiping! Sorry, couldn't resist), I/we are having some issues in our household. THE GOOD: The child I thought would never talk and who eats like a bird, now never shuts up-literally, is either talking, making truck noises or singing, ALL day)-and also eats better. Not great but better than he was. THE BAD: He doesn't have temper tantrums. No, he THROWS. Everything. He nearly took out FIL the other day-threw a small (metal) truck at him. AT CLOSE RANGE. We've tried time outs and they are not working. He does cover his face after he throws, as if to say, I know I did wrong. I am *about* to ignore it. But not sure if that's the answer. Help. THE UGLY: For more than a week now, he has taken NO naps. NO NAPS! And this was BEFORE the time change, so it's not that. I cannot, repeat, CANNOT have a child that doesn't nap. I'll take 1/2 hr-hour even! We do do stuff during the day, so it's not like we're sitting at home and he's not getting his wiggles out. I checked his mouth and it's not his molars either. (He has always been a good sleeper, always. Has slept thru the night since he was 6 mos old and ever since. 1 nap a day (until now) since 14 mos but always 2-3 hours and sleeps 10-11/hrs at night.) With the throwing and now, no naps, I am just about pulling out my hair. (Add to that, a DH who works from home...yikes. Mommy needs a hobby, LOL). Any advice or comiseration needed.
