Everything I have been reading about baby sleep is that a newborn should be awake for around 45-1hr 30 max. My twins have really alert and long awake times. I try to put them down for a sleep but they just lie there awake. This evening one of them has been awake for 3 hours. He is now needing fed again and has not been asleep yet. He is not necessarily unhappy. What is going on here. My older daughter had very short/more normal awake times. For info my twins are 6 weeks old.
