Toddlers' bodies as well as their brains go through growth spurts. When I look back at how my kids cycled in and out of poor behavior, I think it was related to their growth spurts. The cycles of bad behavior usually lasted a couple weeks (not to depress you!).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
