My eldest DSS (they don't live with us) is 11 and has been battling leukaemia for over a year, thankfully he has responded well to all the chemo and it looks like he's nearly out of the woods.
He has dealt with everyhting so well and has been able to go back to school (started secondary).
Younger DSS is almost 9 and whenever they are at our house and start bickering, younger DSS without fail starts saying he wishes DSS1 had died/would die. He goes ON and ON about it. This has started happening more and more often. It absolutely horrifies me because we don't speak like that in our house. Our DCs are pre-school and we try our best so that they don't hear any disagreements etc.
I always ask him politely not to speak that way because I am not in a position to discipline, DH usually ignores it but it is becoming so frequent now we're not sure what to do.
DSS1's illness has inevitably caused upset for everyone and I'm guessing the attention his illness has got is making DSS2 feel left out/forgotten.
DSS1 is very upset when his brother says this to him, the atmosphere changes afterwards and DSS1 becomes withdrawn.
How would you put a stop to this, whilst being considerate to how both children must be feeling? It's ruining our weekends and possibly having a long-term negative effect on the DSSs and also our DCs.
