I was pregnant with ds2. Ds1 was 14 months and I woke up that morning to him crying as he had tried to crawl (presumably) out of his room into mine, only hi babygro had somehow become trapped under the door and he was stuck.
I was aware that some businesses had nurseries attached to them, so when the first plane hit, all I was thinking was "I hope no dc were in there, the combination of late pregnancy and remembering ds crying made my heart break that small dc may have been in the building.
