Thanks for the replies & tips - it's a relief to know we're not the only ones going through it!!

Babymama - yes it is very exhausting. I come out of his room absolutely drained once he's finally asleep.

Jasp - thanks. Sounds like he might come through it on his own eventually, hopefully it won't be too much longer!!

Tippytoes - hope you got some good ideas to use too

Peg - unfortunately he's doing the same thing during the day sleeps, so it's possible that it's having an affect on his nights. Will try playing some soft music.

Santosha - I agree, state of mind makes a big difference. I try hard to remain calm & quiet so that he doesn't pick up on how stressed I feel (some days I try VERY hard!!). Thanks for sharing your story.
