Joanna Fortune: My nephew doesn't get on with my children — and he's staying for Christmas 

December 25 can be an intense day, and families often feel under pressure. Manage expectations

My sister, husband, and their 10-year-old son are staying with us over Christmas, and I’m already dreading it. He’s an only child and used to being the centre of attention. My three older children have never really liked him, as he doesn’t like to share his toys or play group games. I’ve tried in the past to get them to play board games, but they nearly always ended in an argument. I’ve spoken to my sister about the family tension, but she just brushed it off, saying to leave them to work it out themselves. What would you recommend?

There is nothing like Christmas to blur the boundaries we work so hard to uphold all year long.
