or not necessarily sexualised behaviour. One could break down and confide in a teacher after one of his monthly outburst, especially if they are sensitive, or change their behaviour in a way that indicates all in not well at home.
Thankfully teachers are now on alert for abuse after so many failings in the past - and if that happens things will start to move quite quickly.
IF social services get called under that circumstance, and IF you try to minimise or lie about whats actually going on, as well as what might be exposed later - you will lose the trust of the professionals, and then that is the risk that you were worried about when you were questioning contacting refuge/womensaid.
The difference is that if you contact a service for DV, you will be seen as taking steps to protect yourself and, more importantly, your children - even if you are not planning to leave imminently. They will work WITH you and support you, because as a parent (and sadly in this day as a mother particularly) your priority is to protect your children.
However if they get called through a school referral you will automatically be viewed with suspicion - that you have been allowing abuse without seeking support.
And excuses like 'their dad will get a new girlfriend / we will have less money / I still love him/ the kids adore him" will hold short shrift because you are putting your own/his own feelings and wants above them.
And if you tell the kids to never discuss what goes on then that will be 100 x worse, as you will be seen as deliberately hiding things.
So when they are young its probable that one of them will say something after a scary outburst. If they dont verbalise it they will be internalising it, which runs the risk of them displaying the same behaviour. Or they will feel they have no voice/control/ opinion in their own lives (as happened to my friends daughters, one who developed severe hospital worthy/psychiatric inpatient anorexia - its often the only way girls have any autonomy as they reach those crucial years) and the other one who took an overdose after being sexually abused by her brother. And this was a 'naice' family. Well repected professional lawyer husband on 6 figures, seemingly perfect wife, immaculate home.
The kids were late teens before she left. they hold her almost more responsible than him, sadly.
And again, as the kids get older and go to other peoples houses, it exposes how abnormal the relationships in the house are. when they see genuine healthy relationships.
You can sweep it under the carpet when they are little - and little ones are still fairly easy to control, they still take your word as god, and dont challenge. But they will challenge him as they get older, they will disobey, they will go through phases of making shit up, as they learn about it, and is he going to punish them for making mess/ noise/ not tidying up after themselves, answering back/ sneaking out to see people he doesnt approve of /'going wild' in a normal way young people do - is he going to huff and sulk and shout and throw things until they are just scared into behaving in a way he wants and counting down the days when they can leave.
