My son was born 6 weeks early, now is 13 weeks old. He has an upper lip tie , a posterior tongue tie, a high palate, a pretty recessed chin, hypospadias, and a shallow sacral dimple. Several people have suggested that I need to look into mthfr and midline defects. Is there something more that I need to worry about with this mthfr stuff?Also at what age and in what kind of practice should we seek treatment for his recessed chin?Thanks!
