Sensei recently contributed (with a heavy heart) to Callen’s Cause benefiting SIDS research. Callen was a sweet baby boy who passed away from SIDS in April 2017. SIDS stands for sudden infant death syndrome (also know as crib death). It’s when a baby 12 months or younger dies during sleep with no warning signs or a clear reason. Callen’s parents set up this fund to honor their son and fight to end SIDS.
