Would it be weird to get an urn? Other options?

I've had 2 miscarriages. The first one, I was not able to get them cremated, but I did with the second one recently. I have an urn with ashes for our second baby, but nothing for our first. It feels weird looking at the shelf and not seeing an urn for our first baby. The urn we have is personalized with our baby's name and looks more like a piece of decor rather than a traditional urn. Would it be weird to get a matching urn for our first baby, even though there wouldn't be anything in it? All I have from my first pregnancy is 1 postive test in a box in a closet. If it's weird to get an urn, what else could I do to display with our other baby's urn?
