There is no evidence that any children were sedated. The McCanns suggested the possibility initially.
Possibly because of a change in their expected behaviour...
1. They are small children they do tend to wake up.
2.They were known to wake up , they had a chart at home.
3.It was said that MBM reported the crying and a child woke up
4. The parents insisted that a slight noise from a door or a light on would wake them up- they would know this from experience
5. This a the reason they gave for using a particular door for baby listening.
So for them self same children to sleep though lights on- doors open. shutters open wind blowing curtains, abductor rummaging, many people talking and parents screaming then well it is reasonable to ask why do you think this was?
And to add . The parents didn't seem surprised that their children didn't wake up with all the commotion. and suggesting they were drugged by an abductor is
taking the persis... I revert back to how would an abductor know dosage to administer to children without knowing weight height and any allergies which could conflict.
