I love baby changing bags, I've had tonnes
I love the PL ones, very hardwearing and practical. The babymel one linked to us lovely, comfty to carru over your shoulder and has fabbi clips to attqtch to the pram better than a long strap swining away.
I like baby bags as they have lots of pockets, I also bought a rucksack, genius I thought. Well, the first time I tried to find my purse I had to fight through eveything else to find it.
I carry lots with me so didn't use a separate bag for me, I only have started to recently again, so not just nappies, mat, wipes, sacks and cream. If you are going to bottle feed all that gubbins will take up room.
Storksak bags are gorgous but being leather pretty heavy to carry and I hated using them if it rained as we are big walkers rather than car dropper-offers.
I'm now using a small across body bag (in every colour!) for my purse, keys etc and bought a cath kidston saddle bag. Actually that's not quite true, I didn't like it as there was no main zip to close the bag so I returned it and bought one off ebay that is CK oilcloth (wipe clean - genius!) but insted of being 68 quied was about 20! It is slate grey woth cream spots and leather trims. One half holds nappies/wipes/mat/sacks/cream/first aid kit and the other there is a fabbi middle divide) for spare pants for dd, sweets, 3 apples or bananas, bottle of water, etc.
Sorry can't do links
