My almost 4YO is an absolute angel and really kind and sweet girl. The problem is she can have moments where she's absolutely horrific and when she is like this there's just no getting through to her. She's had 2 incidents this week at preschool, one in which she poked a child in the eye apparently maliciously. She was apparently crying that she just wanted me and her daddy all day too and been really emotional. 99% of the time preschool have nothing bad to say about her and she has lots of little friends. I'm just really worried that these are going to become learned behaviours and I don't know how to address them. I never set consequences for something that's happened at preschool but we do debrief and I explain why the behaviour is unacceptable. Like I said 99% of the time she's an angel at home and preschool but problem is when she isn't I'm just at a loss how to deal with it. She is very self-conscious and quite an avoidant personality so we don't punish as I feel that this would just knock her confidence even more. The problem is that even when we try and talk to her about why behaviour isn't acceptable she just clams up and either cries in our face or tells us to stop shouting at her (which we're not) I don't think skimming over undesirable behaviours is helpful but nothing really works either. How worried should I be about this? Is the bad behaviour at preschool likely due to tiredness and 'growing' or a sign of things to come? How the heck do we nip this in the bud?!?!! Thanks x
