I had very sleepy Lo's both times. I had to wake them because they were a little lazy and not good at wanting to feed. Also, I had milk supply issues because my Lo was so tired and not a good feeder. If I let him go longer than three hours, my milk supply would suffer. Just something to keep in mind. I too wondered if my son would ever wake up. He slept for a good solid four weeks and he was about two weeks early. My DD slep for closer to 6 weeks. IT's normal especially at ten days old. Not to worry! Good luck
