My DD 4.5 has recently started saying things like "I wish I wasn't alive, life is so boring, I didn't want to come into this life" etc, etc. She started school in January and that was a big adjustment for her but she seems to be settling a bit better. She is quite socially withdrawn with adults. generally she is quite bright and happy, although she is very sensitive to making mistakes, she would rather not try than get something wrong, or will become angry and destructive if she's offered help. I suppose I would like some reassurance that this existential stuff is not that uncommon and any tips on how to acknowledge her feelings without deepening them? MY DH's family has a history of depression.
