In any case, I've never opened windows as a habit in the morning and never had mould either.
I have trickle vents on my windows and my homes have always been well-built and adequately heated and insulated.
The reason mould becomes a real problem is because homes aren't properly protected.
The mould reported in the property where the child lived is not the kind that can be sorted by opening a window every morning as I do, I realise that. I also have trickle vents on my windows and can afford to heat my home, an option not available to many this winter. Irrespective of our individual situations, it cannot, should not, be denied that some housing is simply not fit for habitation whether or not z window is thrown open every morning. News at 10 on ITV have been reporting on seriously substandard housing for some time, none of them could be sorted out by "a but of bleach and elbow grease" as some on here think.
