I agree with everything jodi has suggested.

I must say that if there may be a chance of you using bottles for EBM/Formula etc then a nappy bag with the seperate hot/cool pockets for bottles is a must in my opinion. It keeps the bottle upright so no chance of spillage & also keeps the temp. Very handy if bubs is ALMOST due for a feed when you're leaving to go somewhere so you can heat it before you leave & it's the perfect temp for when you arrive to feed your bub.

You definately want lots of compartments. If you're going to use the nappy bag as your hand bag aswell instead of carrying a seperate bag/purse then you'll need a compartment near the top of the bag in easy reach for your phone/purse/keys. I have a little hook type thing on my keys so they attatch to the buckle on my nappy bag so I dont have to go searching for them, great for when you have your hands full & need to get them quickly.

I recently got a new nappy bag as the one I used with DD (Kapoochie) was too big & bulky for my liking, I only used it for a few months with DD then used my normal hand bag (a large messenger type hand bag). This time I got an OiOi nappy bag which is nice & slim to hang on the back of my pram without getting in the way of my legs while walking but it still has all the compartments etc I was after. So I'd suggest a slimish bag if possible.

There are heaps to choose from. I haven't seen or had any experience with the one you mentioned so I cant offer any advice/opinions on that.

You're sure to find one that suits your needs & looks great too
