Baby Shower

My ex's mom is such a nice woman, she told me that she'll go on the hunt for baby stuff for me! That's so sweet. I would like to invite her to the baby shower but she's my ex's mom .....and my boyfriends mom will be there....I don't know, I think it's kind of weird to have those families together lol ...though I know there'd be no hostility, none at all ....still weird haha. Anyway, she asked me to specify what I need but what do I need??? Anything and everything is appreciated definitely but I feel rude saying what I want! Like, ok I need bottles and clothes and diapers .....a playard, another crib, a mattress lmao good God I hope people follow my registry so I can get everything I need and not just "cute widdle sockssss" like yes socks are appreciated but I need a damn mattress and breast pump! 40 days left til the shower!! Wow ...
