Question about baby shower etiquette

Hi ladies! My cousins mom (my moms sister and best friend) passed away recently. Shortly after, she found out she was pregnant with her first. 🥰 Her mom would have absolutely been ecstatic about her grandbaby if she were alive. She was the best mom/aunt ever. Just a precious, precious person. My mom and I have been trying to just step in and be there for my cousin, and just let her know that her mama is loving on her through us. So we’re throwing her a baby shower, and I am trying to think of a way to incorporate her sweet mama into these moments for her. If anyone has any suggestions, or has memorialized someone special at a special event like this, I’d love some suggestions!
