Pampers can also be bought at Coop. The nursery my son goes to use the Denner nappies, they seem fine but are not quite as soft as the branded ones. I think from experience & a bit of trial & error that "Pampers New Born" are best for the first couple of months, the other brands we used leaked. For older babies Huggies used to be the best but now I find no difference between them & Pampers.

One thing to look for if you have no brand loyalty is special offers. Every few months Coop does a buy two packs get one free offer & Migros does something similar with 25% off.
