Hi I'll start by saying I'm 17 and just found this site whilst looking for advice online.
About 3am this morning I had a call off a close friend telling me he had just had to step in after his step dad pushed his mum whilst she was holding his 4 day old baby sister, he had heard the baby crying and his mum screaming stop so went to see what was happening. I stayed on the phone a bit and things calmed down (step dad went to sleep in the spare room) so advised him not to hesitate in calling 999 if things escalated again and that I would be along with better advice in the morning. My friend hasn't slept a wink all night so I'm going to go and see him later but what advice should I give him for this situation, he's not sure how/if he can help his mum (he's pretty sure it isn't the first time he's harmed her) but doesn't want to sit back and do nothing either. Thanks
