More than 1,000 calls were made to the ISPCC helpline on Christmas Day, according to the children’s charity.
Many of the calls to Childline were from young people struggling to cope with family problems, loneliness and mental health issues, the ISPCC said.
Throughout the day, volunteers dealt with 1,212 calls, texts and messages.
Margie Roe, national manager of the Childline service, said children made contact with them for a number of reasons. Stress, trauma and alcohol abuse during the season could exacerbate problems.
