I will use any of the 3 brand name diapers, depending on sales and coupons. I don't like the generic diapers so I do stick with brand names. However, when there are no sales or coupons, I tend to purchase Pampers the most. They don't leak, they fit well, and have never given my son a rash.
The Pampers Baby Dry diapers feature characters from Sesame Street. They have elastic sides that move with your baby. The tabs are stretchy too to ensure a snug fit. The tabs are velcro so you can check you baby and refasten it if you baby is clean.
I have never had any leaking issue with Pampers except for when I moved my son into a larger size when he wasn't ready. I thought he needed a larger size but soon realized he didn't when I couldn't get the new size tight enough. The size 4, the size he wears now, is for 22-37 pounds per the package. However, when he was ready for the size 4 he was under 20 pounds and is about to outgrow them at 26 pounds. He has been in size 4 for a year now!
I am happy with Pampers Baby Dry and would not hesitate to purchase them.
