You get over events. They change you, sure, but you get over them. You don't get over people. That's the biggest difference and the best way I can explain.
He wasn't a thing that happened, and so I can't 'move on'. He was a person. He was my baby. As much my baby as the son I have who lives and breathes. And he died.
So I can't get over him, the way I might get over hearing something sad on the news. I don't want to get over him. I don't even know what that's supposed to mean. He was my baby - and yes, of course you find ways to be happy. And eventually there are more ways to be happy than to be sad. But it takes time. And you've got to give yourself the time. And anyone who thinks you're taking too long can take a break in your life.
And maybe they will think of it like this - my child died before he was old enough to be seen or held or touched. But he was still my child. If you've lost a child, or someone you love, or even if you can just try to imagine, you know how asinine it is to think you can or should bury everything about their existence in your past and move on with a clean slate.
