Well, It really matter how old your kids are, if they are 6 or older, I would say you could get a away with explaining to them how delicate little animals, such as, leporad gecio or a lizard. With younger kids I would say slightly bigger animals, such as, cats or a rabbit. Also, I wouldn't suggest letting them play with they same toys unles you wash them very good.
The rabbit can give you baby a sickness, or even if the rabbit isn't sick or doesn't have anything it can still make your baby sick, they can still play around each other. Hope this helps! :) Good luck!
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.
