DoubleTrouble: I had a lactation "counsellor" walk into my room, and without introducing herself GRAB my breast and start mashing my son's face onto it... It HURT, he started wailing, and I started crying. My son never learned to latch, and I had to pump everything for him for months. He needed minor corrective jaw surgery at 6 months old, which was likely a lot of the problem. My younger son latched and nursed like a champ, but only from one breast- the other even he couldn't latch onto (it was also the one that was terrible to pump from).
There may be useful lactation consultants out there, but my experience with about 10 of them in two different cities has been that they have a VERY "driven" agenda, and that if things aren't working it's somehow your fault for not wanting/not trying enough. This ignores the fact that failure to thrive and co-nursing were common issues historically, and the infant mortality rate partially reflects the fact that some babies have a tough time learning to eat, and some mothers don't produce a great supply or have poor anatomy for the job.
