Swaddle her and put her down awake.
For us, keeping an eye on the clock is the MOST IMPORTANT THING.
Disclaimer: Do what works for you, this is what we do.
keep an eye on the clock and keep DD2 up for only a certain amount of
awake time (which at this age is basically enough time to diaper and
feed her). See below for guideline by age. We put her down awake, to
fall asleep on her own. No crying necessary. By not letting her get
overtired, she is able to fall asleep on her own. Also, by putting
DD2 down in her space awake, she does not wake up in a different place
than she fell asleep (i.e. she doesnt fall asleep in my arms, then wake
in her crib and be scared).
swaddle using the escape proof swaddle. I personally swaddle till about
5-6 months old. We thought DD1 hated swaddling, so we stopped at 2 weeks
old. Then we found this method at 10 weeks and she fell asleep for 7
hrs that night. It works great for us: http://www.youtube.com/watch?v=5K4VdZxwsu4
We also have a fan for white noise and a fisher price aquarium
for music/lights to distract her. And, if necessary, a pacifier. I
highly recommend a crib attachment thing, like the aquarium, not a
mobile. A mobile needs to be constantly wound up whereas the aquarium
plays for 18 minutes and has a wireless remote that can turn it on from
