Who has bags for their entire family and how are they set up? I'm getting ready to put my family's together and curious to hear how others have it set up? Divvy up the supplies across all 4 bags? Put the most important and/or heavier stuff in my bag and non extremely necessary stuff in the rest of the families? 3-5 day equipment in mine and longer periods in the other bags? Also, I have a 20 month old. Thoughts on having a baby backpack carrier as my BOB?
