Want to teach my son loving approach instead of fear-based approach.

Often times, during parenting moments – a situation arises where you have to teach consequences to kids. Like I was teaching my son to look at the bread, it has gone bad, so we don’t eat them. I asked : What will happen if you eat it? You might fall sick and will have to go to the hospital.

I feel like I often use this fear based approach and I want to shift it to more loving his body, taking care of himself approach. But it also doesn’t work as fast or is as effective as the other approach. How can I tackle this – any ideas on this please?
