Have been with my DP for 12 months and everything perfect except for his son. I have never come across such a devious manipulative child who can twist his father round his little finger. I have 2 kids of my own, theyre no angels but have tried to get on with DSS who we see every other wkend, but quite frankly his behaviour is beyond belief. His favourite trick is to run off when he is not getting his own way. He's 11 and chooses his moment, when his actions cause the greatest effect, running out of the airport at check in when DD said something he didn't like, running off in Spain when he didn't win at cards, running off when he's asked to change so that we could all go out for a treat.... He argues constantly and his Dad just can't disciple him as he screams runs off tells his Mum and causes he'll..... I'm at the end of my tether, I can't believe I can actively dislike a child this much
