I think we only did 4 or 5 signs (more, eat, all done, drink / thirsty) but they were a huge help.
In thinking about it a bit more Araysar , the thing that really saved us was getting the kid out of our room at like 3.5 to 4 months. Ferber worked really well for us and helped get some sanity back in our lives. Related to that, we bought a thing called an Owlet which is like a pulse ox monitor sock and it helped give us peace of mind that our kid was alive. He wore it through about month 10 when he slept. It was also pretty handy to tell us if the kid was in deep sleep when he was really little and safe to move / put down without waking up.
