The removal of the two-child benefit limit will mean no longer "scraping the barrel every month" to afford bills and food, a mother-of-three has said.
In her Budget, chancellor Rachel Reeves committed to scrapping the two-child cap for those within universal credit.
The change means many thousands of parents with three or more children will receive more in universal credit and tax credits.
Lucy Burns, from Eastbourne, East Sussex, who receives universal credit, said the change provided a "little buffer" for her family of six, including a stepson.
