A heavily pregnant woman who fell to death before her three young children were found dead was "a beautiful, intelligent girl" who cared too much, her family has said.
Fiona Anderson, 23, has been formally identified after she suffered fatal head injuries at a multi-storey car park yesterday morning.
Officers investigating the incident later found the children - named by neighbours as Levina, three, Addy, two, and 11-month-old baby Kyden - at their home in London Road South, Lowestoft, Suffolk.
In a statement issued by Suffolk police, Ms Anderson's mother Kerry, father Michael and sisters, Claire and Laura, said she "cared passionately" but had suffered with mental illness from a young age.
They said: "Fiona was a beautiful, intelligent girl and a loving and caring person, but she had suffered from mental illness since she was young and we believe she was driven to her actions yesterday. This was not our Fiona - she was not herself. She cared passionately about others but often brought stress on herself by caring too much. She was gentle but ended up under too much pressure.
"As a family we were close but she would often push us away, keen to do her own thing and not to listen when we offered support. Life was sometimes overwhelming for her. She was really popular but just didn't believe she was and had forgotten there were people there that could help her.
"We wish more had been done to recognise her mental health problems, which could be masked by her intelligence and creativity. She would often make costumes for the children, who she loved very much."
The family added that Ms Anderson would be remembered as a "girlie girl" who was also a very private person.
They added: "Fiona will be known to many in Lowestoft as she attended Oulton Broad Primary, Lothingland Middle and Benjamin Britten High Schools and will be remembered by us as a girlie girl who loved Disney films and playing with her Barbies and My Little Ponies when she was younger. While she was popular she was also a very private person and we'd ask that the media respect this."
Post-mortem examinations have failed to ascertain how the children died and further tests will be carried out, police said.
