I'm sure it IS just puberty making her moody.

Keep talking to her (even if she's shutting you out). Make time for just the two of you to do something she'd enjoy - even something a bit "grown-up" like a coffee/cake outing, beauty parlour, whatever you do as a woman. Has she gotten AF yet? I got mine a week before i hit 13 and i was a nightmare for about 18 months before....

I think if you treat her like a bit more of a grown-up and make it clear you expect her to act like a bit more of one too, while still allowing for occasional childish meltdowns (she's only JUST growing up after all) she'll come through it.

I think the most important bit (just like with toddlers) is to make it clear that even if you don't like her behaviour one bit you love her to pieces and want her to be ok.

HTH somewhat
