Hi sreynolds,Welcome to the Healing Well GERD forum! This is a great place to ask questions, as there are many here who've had Nissen fundoplication, so we know just what your daughter is experiencing. From my calculation she's about 7 weeks post op, and what you're describing is very normal.
From my experience, many surgeons don't tend to provide a lot of information to their post-op patients. I was told that it takes a full 6 months for most of the healing to occur, and a full year for the rest. Bread is one of the last things to be difficult to swallow post op. Another is steak. Generally well-toasted bread is easier to handle, but your daughter needs to remember to take small bites and chew, chew, chew whenever she is eating.
She is still in the thick of the healing process, and needs to listen to her body. If it's not ready for bread, back off it for a while. She will always have to eat more slowly and carefully. The wrap that was created to keep acid in the stomach creates a barrier to food as well, so she'll need to thoroughly chew her food always...even after she's fully healed.
I would suggest that your daughter back off a little on her eating--especially if the irritation of the stuck food has created some nausea. (Be sure not to let her get sick enough to vomit...you should actually get some anti-nausea meds to have on hand so that you can protect her wrap from the stress of vomiting. I always have it on hand so that I don't vomit...I've found out I can, but I certainly try not to, as it creates a lot of stress on the wrap.)
Here are a couple great eating resources you might find helpful during this healing stage:

I had the surgery in Feb. 2009, and am very happy with the results. I'm sure others will be by soon to add their suggestions and support. Be sure to ask any other questions that arise. If your daughter would like to ask us questions, that would be fine, too!
Give her my best, and tell her to hang in there. If she can surrender to her recovery and follow its lead it will be a lot easier. This recovery can't be rushed. Help her listen to her body and eat accordingly. If she steps up her eating and her stomach rebels, back off again. Once she's had time to fully heal and adjust to the changes, she'll be back to eating normally again. Patience is the key.
Again, glad you've joined us!
Best wishes,
Denise
