Honestly, your current room arrangement seems the most logical to me, since the older two are close to the same age. Would your middle child want to share a room with a sister 8 years younger? Does being older automatically mean you get your own room?
You know your kids best, so you know better than me how things should be. That's just what makes sense to me.
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.
