How big should a baby/diaper/nappy bag be? - storksak bags

I have 5 weeks holiday, ETA and try to get a bag of baby. I'm worried about doing what particular size.

If a mother can give some advice on the following, which would be much appreciated:

* What is the size
* What to put in
* Good grades and / or recommendations
