yes/no regression

[Guest guest]

Hi all,

My son has been doing ABA for 2 1/2 years. Yes/No was solid for 4-6 months

for desired/undesired things (ie Do you want a pop-tart, Do you have to go to

the potty?). In the past 2 weeks, everything is " yes " . As he is pushing

something away he says " yes " . I prompt him to say NO and he says " say go " .

After several promptings, he finally says no. It's almost like he forgot the

word no and hates to even say it on imitation. His other programs look OK.

Any advice?
