HELP! Diapers for EBF babies!

To anyone who is EBF what diapers do you use? My daughters poops are pretty runny and I didn't have a problem until recently with diapers. With newborn and size 1 I used pampers swaddlers which were great. Now that she is 14 lbs and in size 2 she is always pooping up her back! I have tried huggies little snugglers, pampers swaddlers and pampers baby dry and the honest company. I have not found one that works! Not sure if this is just something I will be dealing with until she is on solid food but any suggestions would be greatly appreciated!
