To baby wear or not to baby wear??!

Kaycee
So, I didn't use a carrier with my first one but I really want one with my second one, mainly to be hands free so I can still help my two year old while having the baby. I'm due in August so it will still be warm out when he/she comes. What is everyone's favorite carrier that is easy to put on yourself.. keeps you hands free.. is comfy for baby.. and is good for a new born. 
Ones that I've tried that my friends have make me feel like I'm going to drop their little ones when I bend over or have to move any other way than just standing there. 
Thank you!!!!
