My LO is in cloth diapers (prefolds and covers) and we have a diaper service. She's 4 months old and has begun sleeping through the night (11-12 hours). Hallelujah!!!

The problem is she is SOAKING the prefold, and even though it's tucked totally into the cover, her clothes and swaddle are getting wet.

We've tried doubling up on prefolds which helps some. What else should I try? Inserts or doublers or something like that? I am clueless about might work and what can or can't go next to her skin!
