Aargh! Baby Changing Bag Help Please!

[MammaCat]

Please help! I am so overwhelmed with all the stuff I need to get for my imminent arrival, I feel like I'm losing my mind over which changing bag to choose!

So far I think the Babymel Robyn Backpack looks like the most practical, but it looks bulky clipped on to a pram and although it could just go in the shopping basket, wouldn't I sometimes want to use this for actual shopping? In other threads mums (and dads?) have suggested just getting an ordinary rucksack, but I really want something with all the bits included like insulated bottle bag and changing mat. Would an old fashioned tote be better? All suggestions gratefully received!

Thank you :)
