We don't know. When they were still married he seemed to be a good influence - now they live in separate houses but still seem to be having a relationship. Little boy has complained recently (understandably) that he never sleeps in one place for more than 1 night until he comes here every other week-end. One night at stepdad's one night at his Mum's alternately and overnights here in between. He says 'they are just doing what they want'. Our little boy goes to Stepdad's without Mum sometimes when stepdad has his boys there for the week-end, so our little boy is there with his stepbrothers and half brother. He says that is the only time he has any fun. We assume they are living separately so stepdad can see his boys without them having contact with our little boy's Mum and that they have a normal relationship in between and go on holiday together. Stepdad avoids speaking to my Partner these days and I get the impression he is looking out for his own little boy who is just a toddler. He doesn't seem to be sticking up for our little boy like he used to so maybe he has his own issues now.
Sorry - it gets more and more complicated. The picture I get is that little boy gets very little attention from his Mum and what he does get is negative. He has to do chores (not a bad thing) and look after his little brother and he says that is all he does before and after school and is regularly sent to his room without his supper if he does something wrong. He quite clearly says he can't know how to do chores or look after little brother properly unless someone shows him how to do it and it's not fair to tell him off if no-one has shown him how to do it properly.
He spent a heck of a lot of time in nursery when he was a baby. 12 hours a day except for the days that we had him here and we would pick him up at lunch-time. His Mum was working part-time but still left him the full 12 hours and left him with neighbours at the week-end while she went shopping. Things improved a lot for him when she got married and he suddenly had a ready made family, but it all went wrong.
I have always worried about him. He is happy as larry when here so it is hard to imagine his life somewhere else. We see no signs of dyspraxia, flat feet, balance problems or bed-wetting all of which are being investigated. Partner is going to try and contact GP to ask to be involved in medical decisions, but that won't go down well.
Partner is male and pragmatic - thinks legal things may not work and he would be worse off in care, so until now we have just made sure he is here every 3 or 4 days so we can keep an eye on things, and he is here for long periods during the holidays. But I am wondering if little boy has just reached the end of his tether and needs help.
