Julie it is so hard because it depends on why he is loosing weight, there are heaps of reasons, but stopping eating is an aversion of some type, the old adage a child will never starve himself is not always true for some kids.

Again I can only use reflux as an example it is all I know, but here the tube is sometimes good and bad, I know when I first thought about tube feeding I thought it would be great because they are getting the nutrition and at least you know, but in reflux cases some do great and some do bad, they still vomit or are in more pain cause they have food in their tummy.

Is it bad to want to have him eat and gain and then take it away, of course not, I think all mums would do the same thing, but the tube could cause problems with him feeding himself later in life and that leads to lots of therapy, some kids have it a month or two, others have them for years. And it wont solve the reason of why isn't he eating in the first place KWIM?

Reflux is pain, so it doesn't fit that your little one has it with no symptoms, but it is possible still.

Loosing weight when they are eating fine has a lot more causes it could be absorption problems or different diseases etc... but to stop eating, makes me think there is something going on, maybe even pain etc.. for that to happen.

Have you thought about a feeding therapist (or is this the same as a nutritionist) and with the wait 6 weeks is quite a long time, is there anyway you can ring and see if they can put you on a cancellations list?

Good luck again!
