Alex Milne split up with his partner a year ago and his two children - Rhiann,10, and Billy, 3 - come to stay every weekend and on the holidays.
He lives in a two bedroom flat in Irvine near Glasgow. His daughter stays in the spare room when she comes to visit, but under the 'bedroom tax' he may be forced to downsize to a one bedroom flat.
Alex says he can't afford the £40 a month it would cost to stay where he is but he is worried his children would not want to stay with him if they had to share a bed.
ITV News' reporter Sejal Karia visited him at home:

Bedrooms in some foster homes will be classified as vacant, but the government insists funding for foster carers will be protected.
