i haven't ever put jackson down for his naps awake...i always rock him to sleep. i know it's "better" to let him fall asleep on his own and my rocking him to sleep may account for his waking up after 40 minutes and not being able to go back to sleep on his own. so this morning, for the first time, i put him down awake. he did require help from me in the way of patting his back and shushing for a few minutes a couple of times, but he fell asleep and i didn't have to rock him! now, he's only been asleep for 40 minutes now...so we'll see how he does for the rest of his nap...but progress nonetheless.
