Night Diapers

Allie
What have you found to be the best nighttime diaper for boys??  Has anyone tried the Up and Up brand of night diapers? My son had been doing just fine with the regular Up and Up diapers at night but the last 2 nights has peed through them so we are looking for something better! He sleeps 12 hours straight at night so no diaper changes during the night. Need something to last that long! Thank you :)
