The U/S did not show any signs of narrowing - so we are back to square one as to a cause.

He has most but not all of the symptoms:

*significant weight loss - he is beginning to look like a sharpea puppy with all the excess skin
*projectile vomit, no bile but blood a result from the constant vomitting thus tearing his stomach lining
*lucky to have a wet nappy per day but when he does it is blood stained
*more soiled nappies than wet but still not the one per change per feed that were consistant for the 1st 3 weeks
*lethergy - some days worse than others - acutally come to think of it it's a lathegic day followed by a bright eyed day - odd!?
*some partial signs of dehydration - his fontanelle is starting to sink but still passes the pinch test and has wet lips and mouth
but yet to notice the 'olive' but i am aware that it is a sign of PS


So frustrating... and scary! Off to the GP's soon and to the pead tomorrow... fingers crossed for some light being shed on our situation soon!!! I wasn't aware there was a facebook group (guess there's a group for everything now huh?!) will have to find it and see!

Thanks Groffy!
