My son was in size 6 diapers before I moved to these. The 4T-5T seemed to fit like a size 6, maybe slightly roomier but we've had no issues. My son is only 3 years old, for reference, so I was hesitant to buy the 4T-5T size. The sides rip easily to removal, but like regular underwear, you do have to remove shoes and pants to get these onto the kid. Our daycare found this to be annoying, and we did too, so we're back to regular diapers. My son doesn't care one way or the other and he's potty-training. The diapers themselves feel softer than Huggies and are very absorbent.
Thanks for taking the time to write, Corinne! We've let the team know that getting our Easy Ups can be tricky, but we're glad that he's still comfy in his size 6 Pampers. If you ever have questions or concerns, feel free to call us at (800) 726-7377.
