I like using the flip and now have about 16 inserts. I was using the stay dry and like them for short periods. My baby's skin seems to get a bit irritated if I leave her in them for too long or continuously put her in them. I use a bumGenius to give her a bit of a change during the day or if we are out longer. The flips are great I have 16 inserts and just 4 covers and it works really well. I now have some organic inserts and they absorb way more. I sometimes find I will go to change her and only half of the organic insert is wet, whereas, the stay dry insert would have been soaked. They are great diapers to add to your collection and my husband loves using them. They are not bulky under the baby's clothes.
