Thanks everyone for your responses!

LifeisGood - our paed is at the Mater but the feeding team he has referred us to is not the Mater Childrens' one - it is a private one off site. I wonder why he didn't refer us to the hospital one...? Do you think that DS's vomitting was related to low muscle tone? What are the signs of low muscle tone in a baby?

Doubletrouble and Rainbowbrite - thank you for sharing. I did get the impression that most babies who see a feeding team do so for a very underweight child. My DS is still around the 50% and indeed looks a bit chubby! Both times I've taken DS2 to the paed he has suggested to hopsitalise him and "whack" a NGT in (his words!) but I've said no, unless it is absolutely the last resort. He seemed very quick to suggest it for no particular reason (seeing as DS2 is a good size!).

Maruschke - we are going okay, just, thanks hun. Last week he dropped 40g and this week he seems to have put on 400g! He's feeding 2 - 2.5 hourly during the day and only poos every 5 days or so. We still have bouts of crying after feeds and lots of vomits. Sometimes he seems "normal" and sometimes I am convinced there is something else medically wrong with him. Just hanging out for 4 months, surely it will get better then...
