My son is nearly 16 months and just recently has started peeing a lot in his sleep. So much that we've had two over night nappy leaks. Both while co-sleeping with me. 
Anyway, what does everyone use overnight? I have been using Pampers since he was born with no issues, changed him to Pull Ups after the first leak, thinking they are for older children and might hold more, and woke up to a leak today.
So any suggestions?! Other than DH's that we set an alarm for about midnight and one of changes him?
