DS is 6 weeks. This week he has been nursing much less over the night. He'll take one side for maybe 10 minutes and then fall back asleep. He has one long 4 hour block of sleep and then goes another 3, nurse, and then back to sleep for 2 hours. I try to wake him to nurse from the second side, but he is just too tired. Should I be waking him, or is this a sign that he is just needing less overnight and may be sleeping more consistantly soon? He nurses every 2 hours during the day-- this week he has been every hour from afternoon to evening -- growth spurt, I think.
