Costco brand diapers are great. My son could only use pampers but those are so expensive and don't come with a lot. and my son is size 5 now and we get 190something diapers for the same price as pampers.
they are ok. my son pees alot cause he has a dialated kidney so I found the target ones to work out ok during the day you could smell when he went potty but at night they failed to keep him and the bed dry. I personally like pampers or the costco brand but every baby is different you might like the target brand.
