My son, 5 weeks old, has been very sleepy this week. I think he's eating just as frequently, but falling asleep after 5-10 minutes or so, instead of doing 20-40 minute feedings. In addition, his poop has become much less frequent (1 or two small ones per day, instead of 6 medium ones). I've also noticed his poop this week is no longer "seedy", ever since this sleepiness and poor feeding started.
What does all of this mean? Not enough hindmilk? What exactly causes the "seeds"?
