Here we agreed to never paddle a foster child/adopted child who had been abused or neglected even after we adopt them (for the rest of their lives).
We didn't have to make that same agreement with our biological children, although I am sure if we stated that paddling was one of our primary discipline methods we would be highly scrutinized.
Sorry but I am not a fan of using food as discipline either
And we also agree when foster parenting/foster adopt not to use food as discipline in our state also.
