The problem did eventually sort itself with DD1, but I can't remember exactly when. (The whole thing was such a nightmare!) I do know that she had definitely sorted it out by 13 months, when she was mad about boobs, did continual comfort feeding, and had hardly started on solids at all. I think her multiple allergies had contributed to her problem with solids, but I wonder whether there might have been another physical reason after reading this thread. Now, she is a good eater - finally now she's three!
I always assumed it was psycological, as she was a very touchy baby and I think very OS - I hadn't heard of BW at the time. However I have been so careful with DD2, and the problem seems to be sneaking in anyway. Having said which, she does feed better when she is VERY calm - preferably just waking up or going to sleep. I found the info about Dysphagia quite interesting, especially the bit about crying when they see the breast/bottle, and calming down again when it is taken away. She's definitely fussy during feeds, and not afterwards, so I think we may have to look into that.
