The other two kids were sleeping soundly so for all Kate knew, Maddie had wandered off somewhere nearby. No mystery there.
I would have done the same thing which included taking the long way round on my way back to the bar checking all the time in case she was nearby. I am quite sure that Kate didn't automatically decide Maddie had been taken but i am also quite sure that that reality sunk in pretty quick.
Anyway, we have several witnesses who saw a person carrying a child in the vicinity a short time later, this can only been deemed extremely suspicious in the circumstances.

Wandered off - are you kidding me?
What with the curtains blowing open and the bedroom door slamming shut and the shutter at th window raised, and you expect me to believe that Kate must have thought that Maddie had just wandered off - do me a favor...
So, Maddie opened the bedroom window and raised the steel shutter and opened the window by sliding it to one side, and she climbed out of that window and wandered off, when the patio door was open, and the other door on the roadside of the building could have easily been opened by anyone from the inside?
All she had to do was go to the patio veranda and shout and scream from the top of her voice that Maddie was gone to alert the others but what did she do, she went to the tapas bar and told them Maddie was gone and that "They had taken her"...
Who was "they", do you think?
