Both parents on their 4 May 2007 statements say Madeleine reported the twins crying. The twins, not Madeleine.
That fits with the statements in the files by 2 Leic Police liaison officers in PDL.
"At about 20.00 on Saturday 5th May 2007, I arrived at the apartment where Kate and Gerry were staying, with other officers. During the meeting Gerald and Kate had a number of questions to which they wanted follow up and responses from the PJ. One of these questions was that they wanted the PJ to be aware of was Madeleine's revelation about Wednesday night, when she said that she was left alone during the night. She told Kate and Gerry that she remembered the twins crying and that she wanted to know why neither her mother nor her father had gone to the room to see what was happening."

"at approximately 20.00 on the 5th May, I arrived at the McCann apartment with other family communications officers. We were asked several times during this meeting about questions that Gerald and Kate would like to have followed up and responded to by the PJ. I remember that during the meetings, Kate revealed that Madeleine had spoken with her in the morning of her disappearance and said that she remembered the twins had cried during the night and that she wanted to know why neither her mother or father had appeared."
