What do you dress baby in?

By the time my baby comes it will be mid August. I live in Fresno California where the summers here get to at least 103/107 sometimes higher. So what do I dress baby in? because I know babies cant regulate their body temperature yet as newborns, but I also dont want to overheat my baby either. It's kinda making me anxious. I also dont know what to put on my registry because of this (weather). . Do I put long sleeves, short sleeves, beenies? Please help I'm frustrated, confused.. and I dont have anyone else to ask 🤯😔
