Lesh, have you considered having the tongue-tie snipped? My first DS had a tongue-tie and was totally unable to attach. We had it snipped at 3 weeks and he immediately attached. It still took about 3 weeks to totally wean him off the nipple shields at every feed as he had gotten used to feeding with them, but we went on to feed for 14 months with no further problems. In a young baby the procedure is really, really quick and simple. Apparently it's painless and there is no bleeding. It was the best thing we did.

If you do want to wean, it is best to do it one feed at a time. I would call the ABA for more information and they have a really good booklet on the topic as well. GL.
