First time poster here, hi everyone! I do absolutely believe that some toddlers will sleep through earthquakes. This point still raises question in this case I believe because (i) the McCanns have stated that this was actually an oddity (case in point, one of the twins had, according to Kate McCann's telling of Madeleine's expressed worry on the fatal morning, actually woken up in the evening and cried for his parents) and (ii) Kate, in her own words, kept checking the twins' breathing in those first hours post-disappearance as, according to her, she believed the perpetrator may have had drugged the kids. She actually had them tested but only a few months later (so any drug would have likely disappeared from their system by that point). I'm no expert on this case but I don't think most people would have raised an eyebrow re: the twins sleeping trough the ruckus if the McCanns hadn't themselves stressed out it was cause for concern.
