Anyone use one of those inflatable ready bed thingys for the kids when camping? Going with 3 year old and 15 month old. Thought "my first ready bed" for the youngest as it has side bits and a normal "ready bed" for the 3 year old as needs to be bigger. Or does anyone have any other ideas? Thought sleeping bags would be too big, and when also have to then buy airbeds seperately. Want to try and have minimum stuff to take as only have small car! Going to be interesting!
