Hey there honestly I've been through a few that model bags myself with my two little ones and and finding one that's not a burden to carry is key.
Look for bags made from lightweight fabrics like nylon or polyester, they hold up well without adding extra weight, and make sure it's got multiple compartments so you can organize all the essentials—bottles in one spot, wipes in another, your wallet and keys easy to grab.
That way, you're not digging around forever when you need something fast.
Also, think about the strap design, maybe something with adjustable padded straps that stays put on your shoulder or can clip onto the stroller.
I found that convertible styles work best, you know, ones that switch from shoulder to backpack mode depending on the day.
And for looks, go for neutral colors or sleek designs that don't scream 'that model bag,' it'll feel more like your everyday carryall.
Keeps everything manageable.
Works great.
Oh, and check the overall size, aim for something spacious but not oversized, because overpacking makes it heavy no matter what.
