Hi L.
GEtting your kids to sleep is sooo hard! No one ever told me, while I was pregnant, how hard it is.
Kids don't know how to sleep on their own - we need to teach them. I think you need to put Alexia to sleep while she's drowsy but awake - and she needs to fall asleep on her own - without you holding her. Babies wake up again and again throughout the night - and Alexia needs to learn how to sooth herself to sleep without you. I would do a couple of things: put her in her crib and say "good night" and start a bedtime ritual (I walk my son around and say good night to things in his room - ending with saying good night to 'mama') - she'll start to cry when you leave. Let her cry for 5 minutes...then go in and put her back down in her crib and say "good night" and walk out again...wait 10 minutes - and repeat until she's asleep. There's an awesome book describing this method by Marc Weisbluth - you should check it out.
When my son was 12 month-ish, he went to bed at 7pm...maybe she's a little over-tired going to sleep so late? I have no idea what your nap schedule is but it's just something to consider.
GOOD LUCK! YOU CAN DO IT!
