Context: Routine is what comforts her , more than anything else . She needs to be able to anticipate how something with play out in order to feel safe ( she started screaming during group singing because it lasted longer than usual , I realised that usually we sing 5 songs and that day we \'d sung 6 ... from then on singing was 5 songs , she \'d count down after every song and then we \'d leave ) . She had been struggling with confusing 12 with 22 and 21 . Usually when working with her math cards I would correct her , " that \'s 21 , find 12 . "
