"I miss you dad. I so wish you'd been here to meet my wife, baby boy and my next little boy. I hope I've made you proud."

No doubt but he's proud and he has met your wife and baby boy as he is watching over you all and will guide your new baby boy into this world.

He'll always be with me. Just as your loved ones will always be there with you. I've always said "so long as you remember them, they'll always be with you". A bit like that movie, Coco.
