My DS has never been a good sleeper. He has always woken frequently but would usually go back to sleep quite quickly with a little shush and pat. In the last few weeks though he's started properly waking up and will not go back to sleep for 2 hours. We've tried leaving him (leads to hysterical screaming which I can't cope with at 1am!), rocking, feeding - nothing seems to work. Does anyone else have any experience of this? We've thought about changing his bedtime (currently 7pm) - might this make a difference? Any advice/strategies to deal with this would be great - its killing me and I go back to work in 4 weeks and would love to have it sorted before then otherwise I might get the sack!
