Its not easy when they are so young, but I used to encourage them to think. Example my ex used to always tell the children that his maintence paid for things like a (detail removed by moderator). Basically the pittance of (detail removed by moderator) per month for 3 children was discussed with the children like it was an everlasting moneytree. He used to plead poverty to the children and I would ask them to compare what he has to mummy. They came to their own conclusion; me living in a (detail removed by moderator) with a second hand banger of a car working full time, him living in a (detail removed by moderator) and car and works part time. Things like the silly names he calls me I laugh and I say isn’t daddy silly calling names…thats what people do when they can’t act like an adult. Itaken a while for them to work out but the two have been able to see it for what it is as they have gotten older.
