More than 10 per cent of cases being treated at Crumlin Children's Hospital are due to accidents on trampolines.
A consultant at Children's Health Ireland says these range from cuts and fractures to neck injuries.
The total number of injuries has not seen a significant shift despite people being asked to stay at home as much as possible to stop the spread of covid-19.
Consultant Paediatrician Dr Carol Blackburn says this has not stopped children getting hurt:
"While we are seeing similar numbers of injuries in total, the kinds of injuries we're seeing has changed somewhat.
"We have seen a documented increase injuries from trampolines which makes up 10 per cent of our total injury presentations at the moment."
