I'm gonna stalk this thread, because I am asking myself the same question!
We've had a really hard time dealing with our LO's feedings, as she gets terrible reflux and takes ages to eat (but it's getting better with the addition of a little rice cereal).
And it seems now that we just can't win: We either feed her when she cries (Assuming of course nothing else is bothering her) and don't stick to 3hrs between feeds and it's endless 1/2 or 3/4 feeds, OR we wait the 3hrs and by then she can be in a real tizz, but eats properly!
What have you been doing so far bellaloo?
