Okay, it was our first try. I'm totally not panicking (sort of). We tried the usual MF insert along with a medium JoeyBunz in our 4.0. DS literally woke up in a pool of pee this morning - even his little socks were wet!! DH was completely skeptical of using CD overnight, so I'm currently listening to a lot of "I told you so." Grrrrr. Next idea....
Re: Overnight FAIL!
This. We've never had a leak. I use either a sbish or WCW soaker or a RaR PUL cover over the fitted.
