Help me and my big family

I have a very big family. My 6 children and me. We live in a small house with 2 rooms a bathroom a kitchen and a livingroom. I am a stay home mom and we live off a small amount of money every month. My dream is to have a big family house so my children can have rooms, so they don't have to live in the same rooms they are growing up and they feel very ashmed to live in such a small house and i want them to be happy. So i would like you to help me fulfill my dream and help 6 children to be happy.
