Young family in dire straits

A young mum of three children, ages 9, 8 and 15 months has had to have her partner move in with her as she is currently 3 months pregnant, expecting twins and is struggling with the pregnancy.  She was in receipt of Universal Credit, however having informed the DWP of her partner moving in they have stopped her payments while they reassess her situation.  Her partner receives £50 statutory sickness pay per week, plus she receives £42 child benefit.  Their housing benefit has stopped being paid while her financial situation is looked at by the DWP.  In the meantime rent arrears are building up and she has no money to buy food for the family.  We agreed to send the family £150 to do an essential food shop.
