Let me start by saying I'm really not sure about posting this, as it's not a huge problem. Just a bit of a niggle really.
DH and I both have a bit of a shout at each other occasionally but to be honest we can't keep a straight face - one of us stamps our feet and says "You're Rubbish!" or something equally childish and then we both laugh or try not to!
We have two small DCs, one primary one preschool. They are adopted and one has some behaviour problems and we try really hard not to shout and to be very patient with them but things slip inevitably and we end up shouting "WILL you STOP grabbing your sister's food" or similar. It's usually over silliness or sibling bickering or occasionally danger - if either of them are distressed we are able to remain calm generally, and if they calm themselves down the policy is to say how pleased we are they've done that etc. I don't think we are louder/more shouty with the DCs than I've seen other parents being at the park etc. and I tend to think nobody is MORE shouty in public with their DCs so we are probably average/more patient with them.
But DH has a habit of shouting at himself. He doesn't shout in rage when there is someone in the room but if he is e.g. doing some DIY and gets it wrong, or if he hurts himself it's quite over dramatic.
This stresses me out and if the DC are around/awake they get worried. I've tried telling him this (he'll usually tell the DC there's nothing wrong, he just banged his finger or dropped his hammer).
I think he's being a drama queen, to be honest, but I'm worried it will frighten the DC. Fortunately neither of them were in the birth home long enough to know what DV is (both in foster care from birth). I just think this is unnecessary and it is annoying, he doesn't think it's a problem as he never shouts AT anyone (he's absolutely right, apart from the above banter/us both pretending to be toddlers, and apart from both of us occasionally getting a bit frayed with the DCs).
Is it worth making a fuss about? It does worry me. It's not any worse since having the DCs, it's not directed AT anyone, he is right about that, but it can feel like "if I'd helped him do X he wouldn't be cross". And as I have pointed out he would not do it in the office even if he was on his own in the coffee room or whatever. Though maybe if he was a self-employed contractor he could shout in someone's empty house of course!
I've tried looking up "how to shout less" but they all say "at your child" or "at your partner" and he is probably less shouty than me in both of those situations (I'm reading the tips on not shouting at your children, myself!)
