Is lo exclusively bf? Don't know about the stinky and thick part but I have been told that greenish poop is often because of too much foremilk from switching sides too quick. Doesn't sound like your problem with the other issues, but thought I would throw in just in case. Also, don't worry too much about the 3 to 4 days, my doctor said that it is normal for some bf babies to only go once a week. {{{{{{{{HUGS}}}}}}}}}}
