My daughter was never a good sleeper until 7 months when I was fed up with getting up 4 rimes a night, and never getting more than a 30 minute nap! We Bought the book, "Healthy Sleep Habits, Happy Child" by Marc Weisbluth...you may be able to find it or interli9brary loan it from your local public library, too. It was a lifesaver!
First thing it says that our modern lifestyles and electric lights go against the baby's natural biological clocks, we keep them up much later than we should, to see them after work, or play, etc. when they really need to go to bed at the time it gets dark out. My daughter was going to bed around 8 pm at first, at 6-7 months, I moved it back by 1/2 hour a week, and even now, at 22 months, her bedtime is between 6:30 and 7:00 and she sleeps till after 7:30 am!!! That first two months, she was still nursing, and would sleep 6:30-12:30, nurse, and then sleep form 1:00-7:00!!! It was like heaven!
We also realized that she didn't like to sleep in her room, especially during the day, it was too bright...we got denim curtains, and turned on in a circular floor fan - or in winter a humidifier, and always play a lullaby CD on repeat for her...with the curtains taking out the light, and the fan and music blocking out outside sounds, it helped tremendously!!!
Warning, we did do the "Cry It Out" method - extinction, not gradual extinction (he talks about both in the book)....we did our routine, put her down in her bed, said we loved her and closed the door and left the room. It WAS HARD! The first night she cried for 45 minutes straight! Second night was only 20 min. third night maybe 10 min, and 4th night, she only hollered just as I closed the door. That was it, ever since she has been great in her bed, night and morning and naps!
Naps improved after night sleeping improved...better sleep breeds better sleep! When she was first doing this, she would wake at 7 and we would eat breakfast right away, and then play a little while, and within one to one and a half hours, she was back down for her first nap...usually an hour or more long....then up for a few hours of eating and playing, then an afternoon nap of an hour+. At about 18 months we went to one nap in the morning, and an awake but quiet playtime in her crib in the afternoon, now at 22 months, we are loser to one just one nap of about 2 hours around lunchtime, most days.
Now she does also have pacifiers and a lovey - her giraffe, Jeffery...without those two sleep doesn't go well....we tried to take away the binkies at 12 months, and againlast week - no dice....oh well - we will try again around 3 yrs old.
Good Luck!
