My two kids same age difference but a year older then yours go through this moody phase every six months at the same time for about a month spam...and I just want to get rid of them. They don't do it every other month. So I would try and see if there is anything bothering him. How long ago did this start. Have you moved, had him change rooms, start school, new job...can you link this moodiness to anything. I think it is normal to have this problem on the occasion like we have every half year but not every month or two. Do you get your quiet/not quiet one on one time with him while the other is napping this is huge in our house.
