Hi,
Just got on this site, and you are the first question I found. Boy, that will always be one of the tough ones, to let them fall asleep on their own, but if you don't, just more work on your part. I am a mother of an almost 16 year boy, and a almost 13 month old little girl, and let me tell you, I have learned my lesson with the second one on many levels.
With my son I was a stay at home Mom in a new place (husband military) and knew no one, and had no clue what to do, so I basically did whatever I could to make my son happy, including rocking him to sleep, and did it all backfire. By 5 he was so out of control with me he had to go live with his Dad, cause I could not handle him anymore (now we have a great relationship) So, when my daughter came along I did everything a lot strickter and with CONSISTENCY (think that is one of the most important things about parenthood) and for it I have a wonderful little girl that minds me and goes to bed at 7.30 every night and sleeps till 7.30 the next morning (well okay, still takes a 6 AM feeding, but am willing to do that for the extra 1.5 or 2 hours she gives me after that.
Because you started later it might take you a bit longer, but at her age she should somewhat understand, so if you start giving her very consistent evening routine, so she knows what to expect, with a very consistent time ( I know it keeps you more tide to the house in the evening but it will be worth it and babies crave routine) she will learn at some time. You might be lucky and it happens in a few days or maybe much longer. Just know that when you decide to start this you need to stick to your guns no matter what or else she will learn that as long as she keeps crying you will give in ( and she needs to learn that Mommy is the boss)Good luck, and remember little babies little problems, big children big problems, so stick to your guns.
As far as being a stay at home Mom, I still am too and loving it, but also the second time around I realised how important it is to keep outside contacts, so even though I just moved her less than a year ago I joined every Mommy group, new comers group etc I could get my hands on. As stay at home Moms we get lonely, feel underappreciated and out of the loop so support is to me the most important thing I can do for myself, and I am a MUCH better Mom for it.
Good luck
