Camping with Baby advice!

Hannah
Hi all! My husband and I have decided to go camping in a few weeks around the end of June! We will be taking my 16 year old brother and two of his friends, my step son whom is 5 and my daughter.. Who will be 6 months old around the time of the trip! 
I am sooo excited for camping. I get to make a big list, and I get to organize camping gear and supply's and I get to pack it all and then set up at camp and I just can't wait! I love that stuff! And then at the site I get to relax.. Somewhat. 
I'm really nervous though. What do I need to bring for my daughter? Her bottles and diapers is about all I have on the list 😳
I need some seasoned camping Mommys to help me!
