Private OT required for 4 year old with sensory challenges with eating

My son just recently turned 4. He has never been able to get past the smooth pureed texture. He will now eat completely smooth food items and some crunchy food (goldfish crackers, cheerios, some cookies etc). We are looking for a private OT with training in Wilbarger Brushing Protocol and/or SOS. We live just outside of Calgary and are willing to travel if necessary.  Please contact Cheryl at cjn1@telus.net or call 403-604-4478. Thank-you!
