Been there! "Healthy sleep habits, happy child" is the best book ever by Marc Weissbluth. Every mom should own it. The best advice I can give is to be as consistent as you possibly can and that you will prob need to let Alex cry to sleep. It is rough at first, but so rewarding in the end (after a few wks, depending on the kid...my second was soooo stubborn) when they are able to put themselves to sleep. I found that the more I tried to soothe my little one, the more I stimulated them and interrupted their process of falling asleep on their own. Get them as sleepy as you can, but not overtired, and then just put him down, crying or not. Let him work it out. That's all you can do! Good luck!
