I need advice. Ex slapped 5 year old DC during his contact time for being naughty. He said he deserved it and that he should "have a few more slaps" to "sort him out". DC has likely but waiting to be diagnosed additional needs, and can be very difficult. This is the final straw tbh in years of shit parenting by Ex.
We agreed never to use violence as discipline for this DC, and to my knowledge DC has never been hit before.
I need to protect DC and feel I should insist on no unsupervised contact until Ex can show he won't hurt him again, parenting classes etc. A family member could help with supervised access, or a contact centre. Ex has history of abuse towards me and older DC though not documented by any authorities.
Should I report to SS or will this open a can of worms? I'm reluctant to cause more drama.
Should I get a residence order or will this open me up to Ex contesting it and seeking new contact arrangements? DC have always lived with me by mutual agreement. He may not bother to seek contact by himself.
Is there any other action I should or could take or things I should do? I'm in such a state about it.
