We put our daughter's crib in our room, which I think helped tremendously in getting her to sleep through the night. When she started climbing out of her crib we put a foam mattress on the floor and let her sleep on that (which we moved to her bedroom). This also helped with comforting her at night when she woke up, as we would lie down next to her. Gradually she stopped waking up at night, and if she did, she would go back to sleep by herself. IMO, getting your baby to sleep through the night and going to bed without too much fuss pays off. I'm no child psychologist, but I think by assuring them that you're there whenever they need you, they become more secure when you're not around. Being able to have a full night's rest is imperative to functioning well the next day. Once you have children, you tend to start strategizing your sleep schedule.
