Don't worry, I didn't feel judged.
He doesn't scream for the whole 2 hours, it escalates, then I think I am about to go in and then it settles for a minute or 2 and then it restarts!...so yes a lot of screaming but not the full 2 hrs.
Incidentally I CANNOT tell the difference between his mantra cry and any others

I have not tried WIWO (walk-in walk out?

) and am not familiar (fingers through Tracey's Book LOL)
Will try getting hubby to go in and out...how often?, he really is a milk zombie with me...he knows I've got the goods!
I am glad there is no food tonight, as dad would have been feeding him shop-bought pizza (mmmm nutritious!)
