Unlike cupcake I think there can be too much love ..... one only has to read relationship threads to see the misery caused by that when it is allowed to run riot,, but I must admit to referring to my DDs when not within earshot of my OH as 'my daughter /daughters'. I realise it sounded a bit selfish, and thoughtless.My excuse? I was an only child with not a great sense of sharing, even after meeting my OH, even though I loved him dearly, and he was the rock of my adult life.
However, I never refer to my grandson as my boy (except in a jokey 'Tom and Jerry ' way). I love him to bits, but he is not mine. He is his own person firstly, and after that he is his mum and dad's 'boy'. IMO, anyway.
