I lashed out and brought an OiOi hobo in the blue for when pg with Alister and it was money well spent. It's quite large and fitted everything I needed in it, even though I didn't need a lot for the older ones, it still fit drink bottles and a jacket or two in it. I don't use it as much now (I have a small backpack by Tiger tribe I use mostly) but I use it when I know I need to take a lot of stuff with me. I used to just put in in the carrier underneath, but if I had to, I would sling it over the handles too.
