The bottom pocket is roughly 8 inches tall by 24 inches wide. There is a piece of Velcro in the middle. I would probably store both the covers and the liners in this pocket. Then I would use the upper pockets for teething supplies, rash cream or Vaseline, binkys and similar items. We used disposables just because I had to send mine to daycare and none of the daycares allow cloth diapers, but if you are using cloth, they are much better for your little one as they will get less rashes. (I had one set of cloth that I started out with and did not upgrade when they outgrew them.) Good luck on your new addition!
