My 18 year old stepson has kept to the fortnightly visits but if he misses one, he will double up. He has a pull out bed in the living room as we only have 2 bedrooms. It's not ideal but I didn't think the visits would carry on this long. He has a new girlfriend and bought her here Christmas Day without giving us proper notice. They proceeded to have their dinner and go to bed at 3pm. No Thankyou for the gifts or the meal. No help offered to clear up or to tell us their going to bed. My husband will not disapline his son for anything. He comes here and does what he wants.
