When you have problems in the family, do you let your children know about it or you hide it from them?

Hi, My daughter is 6 and I let her know things if I think that it will not stress her. Since, she is emotionally very sensitive child, she gets affected by things that bother us, as in things that she can sense are making us sad. So, I do not tell her such things. But, yes, I do tell her if there is a problem to which we are also looking for a solution. So, she becomes the part of the whole process of finding a solution to a problem.
