Thanks MantaRay for your views. I just can't help but think it may be something a little more than just not pooing iykwim.

Monnie Yep the farts are definately room clearers lol.
I'll have to look into the "wonder weeks" thing though.

Anyway we are off to the Drs in about an hours time. Sage didn't sleep any longer than 25 mins at a time during the night and he screamed the house down when he was awake His temp is still up 37. I have given him some panadol but it doesn't seem to be doing much (I won't give him neurofen). We'll see what the dr has to say.
