My first son was a professional breastfeeder...gulp-gulp-gulp...10 mins and done. This one, though, is such a snacker. Eats lazily for 15 mins, then he gets off, then 30 mins or so pass and he acts like he's starving again. Eats lazily, gets off, 30 mins pass, starving again. Is there any way I can get him to take a full feeding in one session instead of 2 or 3 mini sessions each time?
