we bought an OiOi bag and it worked a treat! it is in great nic and fits heaps of stuff (especially in the newborn days of needing a few changes of clothes for the JIC vomit moments).

all i recommend really is getting a nice looking bag that you are happy to stroll around with, as you will be using it in whatever shape or form for years to come.

i recently went to the stocktake sales at myer and also picked up a massive kenneth cole leather bag for $100 and am stoked as i can not only use this as a handbag but also with my nappy organiser for when this new bub arrives. that way i have choice between the OiOi lol!

HTH!
