How to reach out to someone who lost a baby

I'm having a baby sprinkle for my second baby , and my cousin is invited . We are approaching a year since my cousin lost her baby which was still born. This would have also been her second baby.

I'm wondering if it would be appropriate for me to reach out to her and tell her that it's ok if she's not up for coming to the shower. We are close but she also likes her space so we only talk about her loss when she wants to bring it up, which I completely understand.

But a part of me feels like I should tell her that it's ok if she doesn't feel up for coming , that I know she still supports me even if she isn't there. I'm just worried that maybe saying this would be uncomfortable for her and inappropriate.. but I really care about her feelings and want her to only do what she is ready to do.
