This is probably a PFB question so feel free to snurk if you wish!
DD is normally a fairly easygoing girl, she's always been sociable and is generally happy being around other children. Normally if someone pushes her, she'll say 'now, that's not nice' and leave it at that, which I encourage ('that was good, you told x you weren't happy but you didn't make a fuss, are you OK now? That's good'). She's always been praised for good behaviour ('I'm very happy to see you sharing so nicely', 'that's good manners' and so on)
Since turning 2 and moving up at nursery her emotions seem to be all over the shop. For the last couple of weeks we've had at least two tantrums a day, usually over not being able to watch TV, having her hair washed or leaving the house. If her cousins (who are older and who she sees quite often) do something she doesn't like, she screams and bursts into tears, and is completely inconsolable for ages where previously she'd say 'that's not nice'. She dpesn't interact with them well and doesn't seem interested in her friends at nursery any more, where previously she was always really excited to see them.
Not sure how to encourage the 'nice' behaviour and being 'kind' to others? I do try to ignore the bad and praise the good, but my ILs are starting to look at her as 'that child' and her cousins are now acting up to it. Is it a phase that will pass or is there a way to encourage her to be 'actively nice' IYSWIM?
