Anyone with a young child feel like no one cares about their loss?

I was diagnosed with a missed miscarriage yesterday. D&C is scheduled for the day before thanksging 😞 (Wednesday). I have a 9 month old baby and it seems like as soon as I mention that to people I get the "oh" (like oh you're okay then, you have a baby tone). No one seems to realize this is a much wanted baby that I'm losing. And don't let me mention this would have been baby #4. Then I'm treated like I'm just being greedy.
