Registry/baby items

Li

First time mom here. 🙋🏼‍♀️ I’m trying not to buy anything for baby yet and mostly wait until after my showers (which will probably be in September) but wondering if there were any *must have* items that I should make sure to register for or items that are useful but not commonly thought of? I’m registering on Amazon first so it could be any necessity! I’m 14 +1 🤗🤰🏼 Due 12/1/18
