My son is 9 weeks old. We are battling the 45 minute nap - every nap. So I am examining what I might be doing wrong. To wind down I swaddle him, turn out the lights, hum a lullaby, then hold him quietly on my shoulder for a minute while he sucks his paci, then put him down. He usually goes to sleep peacefully from that point (until 40 minutes later), unless he loses his paci before reaching deep sleep. When I put him down I am not sure what stage of sleep he is in as I have darkened the room, but sometimes his eyes are opening and closing, sometimes they are just closed. Am I teaching him to sleep independently, or do I need to be putting him down sooner, while he is more awake?
