A sponsored bounce is expected to have raised more than £500 for Children and Need.
Children at Butterflies Day Nursery, of Lakenheath, were sponsored to leap up and down on a bouncy castle by friends and relatives.
Some of the children bounced as quickly and as high as they could for one or two minutes.
In total 60 children took to the bouncy castle, which was donated by DBL castles of Lakenheath, during a week of fund-raising.
Nursery manager Toni Ann Tippett said the children had a great time and that one managed to raise £100 in sponsorship for the charity.
