Mine can 6 hr straight nv slp.... abit worried cos slp is impt for them to grow. How long does ur lo latch per session?Mine comfort latch sometimes. I always let him unlatch himself. Sometimes I fall asleep too as he comfort latch. Sometimes I will just look at him, enjoying the moment. But since my mil is sometimes the care giver at night, she has manage to use her own way to make him slp.
