DD6 isn't often ill but she vomits as a result of a number of triggers. The first sign of a temperature is usually her being sick. She has also been sick following a paper cut and at the mention of a blood test. Talking about being ill makes her feel sick. She now has chicken pox but if anyone talks about it she throws up even though she's not particularly unwell with it.
I have managed to distract her from being sick in the past but it's getting worse. You can see the colour drain from her face as any conversation about illness or blood goes on.
I'm wondering about hypnotherapy. Would that work on a child or is there something else I could try?
