I've got twins myself and finding the right that model was a game-changer. You need something with enough room for double the diapers and wipes, bottles, and that model clothes without it feeling like you're lugging around a suitcase. Look for ones with multiple pockets to keep things organized so you're not digging around forever when one baby starts crying and the other joins in. It's all about that balance of space and not too much weight on your shoulders.
Also, think about how you'll carry it - backpack style might be easier for chasing after two little ones. Works great for us on outings.
