I went to 2 speech therapists n one says may b chewing problem as his babbling is like akh bukh dildee etc, more like German sound, as he doesn't like to chew more n throw if sum thing doesn't like, other says may b sensory for oral as he doesn't like certain food items n have less jaw exercise. I'm really worried about his delay. Plz help me with guidance.
