I was thinking of this because my mother was terrified of strong feelings and would often contradict what I said I felt. So I would say 'I'm feeling really depressed mum because of x' and she'd say: 'No you're not - you're just sulking!' or 'This isn't you - you're normally so cheerful'. Naturally I grew up distrusting my own feelings and ashamed of feeling depressed.
So now I take my children's feelings seriously and (I hope) listen to what they have to say. I might not be able to sort their problems out but I never trivialise them. Not to say I'm not making lots of other mistakes but I'm determined that they'll never complain I didn't listen to them.
