I have got mould and damp feeling in my bedroom and my daughters room i am constantly cleaning the mould away but have noticed it now growing on my furniture and clothes, i have chucked these things away and try to ventilate the rooms and the property as much as possible, there is so much condenation in the windows in the mornings and that's with the doors open and windows too.
Is there any way i can get rid of this, prevent it or reduce it i have a young child and newborn in property and i don't want them to get ill from it.Somebody mentioned just placing some brick or something in the room along those lines.If anybody can help me please give me some advice please!!! :D

Much more info needed

Are there any extractor fans in bathrooms, kitchen etc
