I can't believe it, but I am seriously thinking of using this with ds. Never considered it with dd (3) as once she got to 6 months her sleep improved massively (partly due to using baby whisperer techniques).
Ds is 6.5 months, has NEVER been a good sleeper, but in the last few months pretty much wakes up every hour and a half after about 11:30/12pm. His 'long' stretch of sleep is when he first goes down in the evening at 7pm, until about 10pm.
Recently I've started taking him in to bed with me when he wakes around midnight as he won't settle in his cot. However, sleep is no better this way - I think we keep each other awake and he ends up feeding his way through the night.
We have gently tried to teach him self-settling techniques (eg pu/pd), but they just haven't worked. I am completely exhausted, and feel that my relationship with my dd and dh is being affected. Not to mention my bonding with ds.
I'm not sure I want to hear controlled crying horror stories (as I've read them before), but I would like to hear from people for whom it's worked...
