Im pregnant and my sister is currently struggling to get pregnant, I need some advice

So I am currently 8 months pregnant and getting ready for baby to arrive. My sister is currently going through multiple treatments to try and get pregnant. I know me being pregnant is hard for her, because if the shoe was on the other foot, it would be hard for me. Can you all share some ideas on how I can make my baby arriving special for her, but not like I’m rubbing it in. I’ve been thinking of incorporating her in some way, without being insensitive and pushy. Thanks!
