Baby carriers

Bri 🇺🇸 • Expecting our 1st baby this November. Can`t wait to meet her❤️ ICP mommy • #itchybaby
Do any experienced mama's recommend a certain type of baby carrier? And why that one? 
My sister is a baby bjorn fanatic. I am trying to do my research and there are just SO MANY options. We live in a city where the summers are VERY hot (like in the 100's) and so I don't want something that is going to be awful to wear: thick, padded and plus the extra body heat exchange between me and the baby. I don't mind it in the winter though.
