DD (2.3) has just started nursery a couple of mornings a week. Her first session went really well considering she has never really been away from me. She was reluctant for me to leave but settled fine and played quite happily with various toys, no tears etc. I have noticed though that her coping mechanism when she is unsure or feels threatened/nervous is to shout, usually "NO!" at people. This has become more obvious as I have dropped her at nursery as it is all very new and there are new people (the teachers) addressing her and trying to engage with her. She can be a bit like this at school pick up (has older siblings) when other mums, dads etc try and talk to her. Admittedly I have usually just got her up from her nap so she's a bit out of sorts and still waking up, but literally all anyone has to do is say hello and she turns her head and says no! in a grumpy way!
I suppose I'm looking for tips on how to deal with this as I admit I find it a bit embarrassing and find myself apologising to people, but she is only 2 and still learning social niceties. Her language is very good for her age so she doesn't struggle for vocab to express herself. It's just trying to get her out of this instinct to turn away and shout no, how to encourage her towards "better" behaviours? I know it's awful when your little one cries when you leave them, but in some ways that would be easier to deal with than the shouting, it just seems more socially acceptable IYSWIM?
Or should I just roll with it for now (whilst gently reassuring her everything is ok and people are just being friendly) and cut her some slack as she is so little and starting a new phase in her life?
