Sounds like you're doing the right stuff...it's probably just some kind of phase--plus maybe it's a personality thing. Consistency is really important and will help no matter what else is going on. Also, pay attention to patterns of behavior and see if you notice anything recurrent--e.g. Time of day, setting, certain foods, transitions, routines. Then you can be more proactive if you find you're dealing with a certain issue over and over.
