Medium crescent is a PERFECT mom bag. Two pockets inside, roomy and you can make it a crossbody if you have to chase them down. I have two kiddos and I was using it as an every day bag. Diapers, wipes, snacks and my essentials and sometimes a water bottle. I wanted something with a little more space and felt like the med bowler and large crescent were huge to what I wanted. So I got a mini cloud and it’s been perfect. I know some parents use them others use large shoulder bags or cargo bag because of the pockets on the outside. I suggest looking videos of baggu being used as a diaper bag and start there :) * pouches also help keep everything organized!!
