The report also criticises other shoppers who pile on the misery with unfriendliness and “a cavalier abuse of disabled facilities” such as parking spaces.
The survey commissioned by The Family Fund found that more than three-quarters of parents believed the multiples do not provide appropriate trolleys or have wide-enough aisles.
Over half of parents with disabled children felt supermarket shopping was “needlessly difficult” or “impossible” for them.
Criticism was also aimed at supermarket staff with 70% of respondents saying that the employees manning childcare facilities were untrained to look after disabled children.
Chief executive of The Family Fund Marion Lowe, said: “Our families dread their visits to the supermarket.
“It really is time for investment to be made to improve facilities and staff training so we can turn this situation around and ease the discrimination they feel.”
