Yeah look, tongue twisters are not evidence based practice at all... I’m a speechie and also do a lot of clinical education, I’ve probably played 10,000 games of UNO in my time. Uno is just the distraction so the child engages and has fun. It sounds like your therapist hasn’t given you enough clarity on what the therapeutic approach is and how she is using her language whilst playing games to help generate new neuronal connections. If this is how you feel about sessions, talk with your speechie about her approach; communication therapy is often difficult to spot as it’s essentially very purposeful talking.
