I don't carry baby stuff. If only 1 cam & 2 lenses with a flash should have space for baby stuffs. Best thing I like this bag is when it open nothing will fall off, it does not look like a camera bag. happy hunting.
consider a kata 3n1? using it right now as a travel cum camera bag, can easily fit my carry on luggage + 1 dslr body, 2 lenses, tripod (carried externally via tripod holder), flash and other accessories.
