I agree with "go with your insticts..". That always worked for me. It is really hard as somebody mentioned here already being in a new place and being a new mom, one tends to question everything. So, be a confident mom trusting your guts (and getting your homework done in terms of technique with some helpful lactation lady, they are supposed to come to check on you, anyways) is the best way .

Oh man, how I wished, many, many times, that my 24/7 eater would get tanked up in 15mins. I did get a nursing necklace, a great thing, when my child got older and disctracted and the close pins pinned all over my shirt stopped working. Necklace, pompons, stuffed toys, aluminum foil, whatever to keep her focused did help a bit. And changing every 3 hours also sounds too nice, we ran through pampers like nuts, sometimes 3x an hour .
