Donovan: Alex look out your windown there is a lot of snow.
Alex: No
Donovan: Alex, yes there is and it is snowing outside.
Alex said firmly with a finger pointing: No!
Donovan: Alex there is too snow outside. Mom there is snow outside and it is snowing.
Mom: Yes, Donovan.
Donovan to Alex: Alex all you know how to say is no, no, no, no.
Alex: No, no, no
Mom: Donovan we should sing a yes song not a no song.
Donovan: Yes, yes, yes, yes,
Alex: yes
Mom: We just have to teach Alex how to say yes instead of no.
After listening to several conversations like this on the way to Park City and a little bit on the way home before they fell asleep I now believe that Alex hears no too much because I or Allan say it a lot and Alex has figured that is the only word he is going to say. Mind you he can talk. He just chooses not to.
