Query: Diaper leaked after 7 hours on the first night

I bought these because my 6 month old started leaking with her Pamper Swaddlers. These said that they were for overnight protection and would last 12 hours. When I opened the package I was surprised to see that these are thinner than Swaddlers and plastic feeling. I can handle that as long as I don't have to clean urine off of my daughter, her pajamas, and her bed every morning. She sleeps 12 or so hours some nights, but still wakes up for a feeding on most nights. When she woke up after 7 hours for a feeding, her clothes were soaked. Very disappointing. Pick up a small package before you buy the value size to see if they work for you. These diapers did not work for my daughter.
