Should I report this to the supervisor? Update
Thank you for your replies. I did report it and the supervisor took it quite seriously. She said with so many issues its best to get a new therapist and I did agree. So we will be having a new therapist soon. I hope it's for the better!
During today's aba session, my son suddenly started crying very loudly. So my husband and me knocked on the door and went inside the room. The therapist told us he banged the yellow couch as he was too excited. He was holding his eye and crying. She told him "U need to be more careful next time". Once he stopped crying, he said "I am very sad." I asked him "why are u sad?" He said "Ball banged my eye". The therapist responded with "Which ball, ball didn't bang your eye." At that moment, My husband and I were confused as to what actually happened. My husband did notice that his eye was red.
After the session I asked my son again. He said "I was lying down on the yellow couch. Teacher was sitting on the rug. She threw the light ball (which has spikes) on wrong side and it hit my eye. Eye got closed. I couldn't open eye." I asked him "But teacher(he calls his therapist teacher) said you banged the couch". He replied "A(his name) did not bang the couch. Ball banged A in the eye".
I do know that they were playing with the ball cause I had heard my son say "Throw the ball on the couch please". Though the door stays closed, I always keep an ear on whats happening inside.
Mistakes happen with everyone. We understand that while playing kids can get hurt. However I expect honesty. My son is very clear about what happened, he is just 3.5 and does not what it means to lie. I am thinking of writting to the the supervisor. This is a small incident, however it's about trust. What do you think?
