My partners son lives 90 miles away, he still has a house nearby his ex wife's house so when he has his son he takes him there and I stay at home with our baby and my teenage daughter. We would much prefer to bring my partners son to our house so he can spend time with us all as a family and get to know his baby sister but his mum says that the journey is too tiring for him. He would be collected from school by his Dad on a Friday, stay with us over the weekend and then be dropped off back at his mums house Sunday tea time every other weekend. Does this seem unreasonable?
