I had a nappy bag/back pack with mackenzie which I got from K-Mart which I purchased because I didn't want a bag which I could hang over the back of a pram,but this time around I'm going to go with the Great Expectation brand. A few mums from Mothers Group have them and they are great. You can get them brand new on e-bay for around $60. I think they are a lot more expensive from baby bunting etc. They are the type you lay on the ground and use as a change mat too.
