Love all the bag stuff! Though I found I didn't use mine much (can't even remember what I even went for now!). I never bottle fed, so needed to carry less stuff, There'll be no expensive bags for me this time but if there were I'd prefer something with a longer shelf life than just nappies (maybe a new Orla Kiely bag could be on the cards for my Sept birthday!).
I swear by the skip hop pronto (I think that's what it's called - the portable changing mat). I just bung stuff in that and use and attach it to whatever bag I'm using (which will by anything but my mulberry bag - I love handbags/bags and have more than I should but that one is for me alone and shall never be sullied by having a nappy or spare clothes in it!). I also have an ancient Orla Kiely bag I can use. The great thing about using washables is that you bung anything dirty in a wet bag which means it doesn't get a regular bag dirty.
Frau, sling wise, I use a v small across body handbag for essentials (wallet, keys, phone, snack bar) and then just use the skip hop pronto with a wet bag. Though if I'm out and about for longer I just load up whatever regular shoulder bag I'm using.
Bags really come into their own with older babies, where you're packing snacks and water cups and the like. Under 6 months and breast fed, you can travel light.
Nigh on impossible to see the World Cup here in the US. Would be easy to forget it's even on! I'll try and watch some stuff online but tbh I prefer watching the Tour (which means summer to me!).
