Brief background:
I have a 6 year old and split with his Dad when he was just a few months. Contact since had been sporadic (sometimes going months without contact), but the last year or so has been going well.
I met my now husband when DC was 18mo. We now have two more DC aged 3yo and 1yo.
At first my DC called my then partner by a nickname (he just decided not to call him by his name!) but then soon changed to his first name. When our first DC came along this changed (completely his decision) to Daddy "first name". He's since dropped the "first name".
So now he has two 'Daddys' by his own choice.
My ex thinks that we need to make it clear that he is his only Dad, and that my husband is step dad. He has been having conversations with him to this effect and DC is now asking that he not go for overnight contact, I think these conversations make him uncomfortable.
I don't know what to do. Is there any harm in him having 'two daddys'? Certainly when he asks questions he is answered honestly, but it is my belief that this should be very much child led... what do you think?
