My son was 4 when my mum passed away almost 4 years ago and he wanted to go and say goodbye to her, he wanted to go out to the gravesite to throw a flower in etc. He was asked the whole time what he wanted to do as thats what i wanted. Not long before my mum passed away his great pop passed and he wasnt allowed to attend the funeral and he wasnt happy about that as he didnt get the chance to say goodbye to him

I just think it all depends on them, what they want to do to say goodbye to the person
