Yes, I knew there would be condensation, everyone told me there'd be condensation, but how do you deal with it? I'm spending 20 mins every morning wiping down the windows which, I know, in the grand scheme of things isn't much, but if I don't get a chance to do it before school run and am then out for a few hours, it doesn't get done. Things left on window ledges are going mouldy - even wooden photo frames

Would a dehumidifier be the answer? I'm reluctant to pay for the electricity to run a dehumidifier but if that's what it takes to counteract the ensuing mould, then so be it.
