Thanks all again - there haven't been any major changes at kindy - they suggest it is a phase and that other kids are having a similar regression as we just had the easter break. They have however promised to keep an eye on things and she did seem to have a great day today, she doesn't want to go Monday though as she wants to stay home and work :-)
Anyway I made an apt with an ED psych today, we'll meet next week to discuss if testing is appropriate or if a plan can be put in place to support her instead. Now I'm freaking out that it's all in my head and the Dr is going to think I'm a neurotic mum. Guess lots of you have been through this too!
