Absolutely love this bag. I went with the full size & am so glad I did. It doesn’t look big on but it fits so much! I always have my wallet, a diaper or two, & wipes as shown here but can easily throw in a couple toys, a spare onesie, the mail, a snack I decided I “needed” while grocery shopping, my Bible, etc. I don’t see myself ever loosening the strap (I’m 5’6 for reference) but am so glad it isn’t the type of strap that leads to a loose strap dangling about (Idk how else to describe it haha!). Also, sometimes inner pockets can get in the way of just throwing stuff in there (if that’s your preference) & that isn’t the case with this bag at all! All in all, it lives up to the hype for sure!
