You have to detach from the words. They live in a different reality - a vacuum or tunnel that they have created. This is a LONG process. I am very sorry for the interaction - I have been close to this situation as well - my kids are older though.
Show your kids how strong their MOM is...that SHE is the one they can count on - that she will GUIDE them through this storm - because NO ONE is more important to her than them!
It is the greatest gift you can give and the greatest blessing you have!
