Okay, here’s an odd one. One of the ways we help children grieve well is by making them pick up their socks.
One big temptation for parents of a grieving child is to go soft on them. They have been through a lot and so have you and you ache for them. But you need to keep holding them responsible for their behavior. Ephesians 4:26 suggests we can be angry and not sin. In other words, we are still responsible to manage our behavior even when we are feeling bad. Be sympathetic for their struggles and hug their sadness but at the same time hold them accountable for their actions and expect obedience.
