"When Madeleine was small she would cry a lot. She was a very active baby who did not sleep well. She liked to be carried. She liked people to move around with her and to sing to her. Kate and Gerry found that she craved a lot of attention and were grateful for the help from other members of the family.
Madeleine would normally go to bed around 19:30 ' 20:00 and Sean and Amelie around 18:30 ' 19:00. As already mentioned, together Kate and Gerry were very precise about sleep time."
Precise but changed the missing girl's bedtime in PDL - How interesting

"Because Madeleine did occasionally have bad nights, Kate arranged a bonus system. She would get up in the middle of the night, would go to her parent's room to ensure they were there and would return to her own bed. This situation had gotten better before they went to Portugal."
"I had a conversation with Kate regarding care of the children in particular, leaving the children to cry until exhaustion and Kate and I both agreed that this was not correct and that the attention should be placed on calking them down."
Why would Kate want to discuss such a thing in the first place?
"Both Amelie and Madeleine have taken 'Calpol' (paracetamol) to control fever, but nothing more."
"Precisely related to this routine at home is why Kate rejected the idea of using the Ocean Club facilities and
lay the children to sleep on one of the mattresses in a common area."
