louisehi laura! for me, it sounds like she is a toddler!! i have 2 girls (ages 2 & 5) and they went through similar phases from about 16 months until 3 yrs old. my son with swcah is 14 months and has a temper, but no different than the girls. in my opinion, if her levels were ok, she is growing as she should be, and is not fighting a virus at the moment, she is just asserting herself like a lot of toddlers do at that age. hope that helps!!! sometimes it IS tough to discern between cah behavior and normal age appropriate behavior, but my hunch is that most of the time it is just the child, cah or not!
