when u use carrier for babywearing, where u keep things like hp n ezlink card for easy access? i like backpack but it's not easy when i need to reach my bag for things... a sling would work but i also scare it gets tangled with my bb legs on the side i carry. also more troublesome if i want 2 hands free to carry purchase. i tried a waist pouch on the front of the carrier. doable but adds weight to carrier. jus wondering how do other mummies tackle this?
