Ok so in August me and my son who will be 8 months in August are planning on flying to Arizona to visit family. It will be an  hour and 45 min flight.. I need to know on what to take to keep him entertained, and if he'll need to be buckled in his car seat the whole time.. Do I need the base to his car seat? I just need to tips and ideas this is his first time flying.. Are there tricks to keep him happy and no grumpy? I'm a little scared because I don't wanna annoy any other passengers if he starts crying..
