Hope things get better soon Rickman, I agree with the majority that the behavioural change may be due to tiredness. The eczema can flare just out of stress and being in a completely new environment on her own is enough to get the flares.
Ds started 3 weeks ago and his eczema is back, he didn't start talking until last week (his teacher thought he couldn't speak English ), but although clingy and silent he seems to love the school to pieces, he has even asked to be taken to it during the weekend. Now, at home his behaviour has been more challenging... I think he is tired. We have a longer day now.
