Hi! Yes!!! I feel the SAME way!!! We had EASY schedule going when my son was 1mo-4mo and then when I went back to work it all fell apart. He no longer sleeps if you put him down awake, along with other problems that we've allowed to creep in. But I just wanted to say that it sounds like you are doing a great job! I know how difficult it is when baby won't go to sleep. My son is 7 1/2 months. He'll sleep in a heartbeat if I nurse him or walk/rock him (or let him sleep on/next to me, which I admit I've done numerous times in my sleepy over-worked state!) It's so tempting to just go along with it because the other way is miserable... but that's why I am where I'm at right now. (He wakes with every new sleep cycle because he's forgotten how to self-soothe himself to sleep). Keep it up, and I'm totally new here but it sounds like there are a ton of people to help, so hang in there and I'm sure it will get easier.
