But you should not worry.
You are already on the right track if you are talking in terms of 'Dippy Dora'. That's all it will be. Cirhosis speaks good sense; you would know by now if it was a big problem.
In my first teaching job in East London, I had a situation that I worried about for at least 48 hours. I had moved (let's call her) Amanda from one group to another because she was being a disruptive pain (but a very engaging one). Then I got a letter from her mother asking to see me. I was terrified. I sought advise from my colleagues, and I was v pleased I did because they were brilliant. They told me to just listen to Amanda's mum and see it as an opportunity to learn about Amanda (who, I add, was an absolutely georgous child, but a bit difficult in a class of 40).
Amanda's mum turned up, by which point I had extorted a promise from my team-teaching colleague that she would be in the adjoining classroom if needed.
Long story short; it turned out that the mother was herself at the end of her tether with her Amanda and we ended up agreeing to keep in touch with each other and support each other using stickers as a reward for good behaviour at home and at school. I knda felt for Amanda because her game was up, so to speak, but in the most kind and loving way possible.
Point is; I was terrified and Amanda's mum was pretty nervous. I had the benefit of excellent advice from my colleagues and it worked out very well and I still treasure the letter I had from Amanda's mum when I left.
Believe it or not, every teacher I have worked with has this sort of problem-solving attitude.
Do not waste 48 hours of your life worrying.
When you have your pe, write down in bullet point form what worries you. Start off by active listening.
From a teacher's pov, you are an engaged and concerned parent and that is pretty much all a teacher could ask for.
(secretly thinks that Dotty Doras and Amandas make it all worthwhile)
As a slight aside, most teachers will be worried about the forthcoming public spending cuts.
Promise me you won't worry and
Most teachers (well, all I have met) are very very nice people and will want to work with you.
In five years time you we will all be laughing.
