In desperate need to buy a home for me and my children

I need too buy a house for me and my children, I am currently living in my parents house with my three children twins of 23 months and my newest baby of 6 months, We are all sharing a tiny box room. My almost two year old twins are still sharing a cot as there is no room for two cots in the room I am in, we despratly need our own home, I am a full time single mum on benefits so I can not afford a home, I can not afford to save as all the money goes on food and clothing bills rent, ect there are 9 of us living under one roof, the local council will not help me so this is my last option thankyou for reading and thankyou for helping me and my children buy our first home it means so much.
