There has been a lot of family disputes over the past few years but things have been particularly strained with my brother, his wife and their adult son. We have been seeing them occasionally but each time we see them they get cooler and cooler with our kids (3 and 6 years). The last time we saw them they didn't kiss our kids hello but everyone just stood about awkwardly. Then when we sat for lunch they didn't try to have much rapport with our kids but I caught their son pulling funny faces at a child on the next table while he had pretty much ignored ours. Then my dd tried to get my sil to do some colouring in with her by just talking to her about colours etc and the sil talked with her a bit but didn't join in when that was what dd was asking for. I don't think they should take their feelings about us out on our kids so I challenged my brother and said that I felt they were cool with our children and he said they had "mixed feelings" about our kids because of all the conflict us adults have been having. I was so upset and think it's completely wrong to behave like that, to be passive aggressive with children. I suppose it's a bit of an aibu?
