Doesn't it seem unusual to turn lights on to check that quiet, sleeping children in their dark bedrooms are asleep? Turning lights on means that they might be woken up, which is the last thing parents want to do in the middle of the night.
First, we do not know what kind of light it was. Second, the room was probably, considering the remoteness of the property, pitch black. Third, many kids are perfectly capable of playing without making much noise, while they should be asleep. Fourth, these kids were suspected of being on spectrum, and that usually comes with plethora of sleep issues. So controlling if they were really asleep might have been necessary.
Usually the kids have more than one pj set, these kids, as we know from Malehya, were also sometimes put to bed in their day clothes (it was so at that particular evening). The clothes the children wore to bed were what they wore when they went missing. There was no space for guesses.Don't the children put on their pyjamas at bedtime, and is it that hard to figure out what their pyjamas look like?
How does turning on a light and seeing children asleep relate to getting children ready for bed and wearing pyjamas?
Daniel was busy outside while Malehya put them into bed, so he did not see what they were wearing at that time. The only time he saw them after they got to bed was wen he checked up on them.
