How do I approach this?

La

Ladies, I need advice. My MIL and SIL have planned a baby shower for me. Really sweet. But, it’s been planned for over a week now and they have not once texted or called to even say they want to give me a shower. They called my husband and told him a date and list of people they were inviting. I really want to invite my mom and sister, but they haven’t asked who I want to invite or told me ANY details. Granted, the shower isn’t until July 14, but the fact that they haven’t reached out at all makes me think they won’t ask. I feel it’s rude for me to make the first move and call or text to say “About this baby shower I heard you’re giving me...” What do I do?
