We use Huggies night time diapers. I have also noticed a difference as to where I put the fasteners. I do have a boy, so maybe that make a difference, but I fasten them as high up on the diaper as I can (pretty tight.) If lower, then there is less absorbent material below the fasteners. Do I make sense? Seems to help. Also, depending where you are, babies r us sells diaper doublers that are like a maxi pad but w/o the sticky side. I used them a long time before I switched to Huggies night time. The diapers pull the wetness away from the skin better for us; less redness.
So, those are a few of our "discoveries." lol Don't know what we will do when he outgrows sz 6. He is only 12 mo! Not suer how the pull ups will go.
