Feeling a little jealous

Unfortunately I’m pregnant at the same time as my sister-in-law. 4 weeks apart. This is my second baby tho. I’m a little jealous over how much my in-laws are doing for my sister-in-law’s baby tho? They never did any of the stuff for us like they’re doing for her such as like custom shirts, throwing a huge gender reveal party with custom cakes, cookies, and catering all the food. They’re paying for everything. They also haven’t even asked about my baby or pregnancy, yet they talk nonstop about my sister-in-law’s. I feel invisible. My husband doesn’t care but it’s starting to bug me a little :/ mostly because I have no support from my side either and I just feel like I’m missing out. I’m just trying to tell myself it’s not that big of a deal but it also doesn’t help that my sister-in-law has been openly competing with us since we all got married a few months apart in 2019🥴 any advice?
