Hi M. G! I remember reading an article about things having to do with newborns that you (parents) may or may not know but I cannot remember where I read it. So in my search I found something from www.associatedcontent.com in the health & wellness section...
'Newborns definitely sleep a lot but if yours seems to be sleeping too much, there could be a problem. How do you tell if the baby is sleeping too much? If the child misses a feeding completely, this could be cause for alarm. If the baby simply sleeps past the usual feeding time, no worries, but if he/she continually has to be awakened to eat, call the doctor just to touch base with him about the issue. Babies generally wake long enough to eat and be changed, and may possibly stay awake for an hour or so, but then they normally drift back to sleep. If you have to wake them to eat, then they fall asleep while eating, consult the physician.'
I agree that as parents we sometimes do not know the difference between fear and instinct. So what's the answer? In my humble opinion, get answers until you feel comfortable. That's all you can do.
Keep up the great job and Happy Mother's Day!
