There are some things about my DF that have made me start to question if I should leave DS who is 3 at DP's house unsupervised, which I have done previously for half-terms and school summer holidays when I had to work.
My DF is loud, can be shouty in general, and especially when he is cross he actually bellows which can be a bit intimidating I have witnessed a few major outbursts in the past couple of years, having been on the receiving end once, and I can only imagine how it makes DS feel. One time I was there to comfort him. Another time I was not though, and in his somewhat limited vocabulary at the time he told me it made him feel sad.
DF often teases/calls DS a name him when he mispronounces things (not just the normal light-hearted laughter or amusement when kids say things in a funny way) which I find out of order especially for a 3 year old. I'm not sure if DS minds just now, but I am quite triggered by the fact that DF did the same thing to me when I was a child (I hated it so much that at age 7 I told him I was no longer going to speak to him.)
DF can also be very stern/disciplinarian, shouting over little things, and has said things like Boys don't cry in a reprimanding tone when DS cries, although I'm not sure how often he cries anymore as he is a bit older now.
I expressed my concerns to DM who has said she will step in if there is an incident, but recently I have started to realise how dysfunctional some of his behaviour is, and question if DM will actually recognise it all or would write some things off. For example sometimes DF speaks to DM in a bullying manner, and she doesn't even react. I don't know if DF has done that in front of DS or not, but I would not be comfortable with him witnessing that behaviour, particularly without it being challenged.
I don't have the best relationship with DF and since my mum comes to visit and babysit often I don't go round to theirs much.
All that being said, deep down DF is a good person and loves DS very much. DS does enjoy spending time with him and ask about him and I would like them to have a relationship. I just feel it may be better if I am there so that I can address any negative behaviour I see.
