I’ve been using this diaper bag since my twins were about 4 months old and it has been so useful. It’s a large open main pocket with a few interior side pockets and I like having the option of stuffing it full of stuff or using smaller bags to compartmentalize a few things. It’s large but not too deep in my opinion, and structured enough to not lose a bunch of stuff in there.
I found it especially useful when I was carrying a giant water thermos and formula for 2 babies, bottles, and still needed room for their other stuff. The exterior pockets are useful to me as well so I can have a quick place to stash things. Now at 18 months old I can toss in some shoes, clothes, toys and books, drinks, and snacks and have room leftover to shove some random stuff in. It’s a very flexible diaper bag.
