How much of something does it usually take to figure out you should not eat something? I am getting ready to start the puréed stage, and am nervous.

Don't be nervous. You won't be able to eat much, and if you stick to the usual suggestions, cottage cheese, yogurt, cream soups, you'll be fine. You won't have a tummy explosion. Don't worry.

It the beginning usually a few bites let's you know it was a bad idea. This is the best time to get to know your pouch! Learn her likes and dislikes and how she operates. Also just because she does not like something today in a few months it might be different.

My NUT suggests trying new foods one at a time--- a "thimbleful" to see how it goes!

I introduced one food at a time - just a couple of bites. If I had a bad reaction, I would wait a couple of weeks to try it again.

I'm 8.5 months out and still have foods that don't agree with me. I tried cherries for the first time since surgery yesterday - OMG, it was excruciating pain!

i also just did one thing at a time. i started with cream soup and found one or two that were very tolerable. i ate them for like 3-4 days then found something else new to try. worked good.

This is a great question!
