Hi Courtney,
I have 2 kids, a dd who is 2 yrs 2 mths old, and a ds who will be 5 mths on the 11th. Both started short napping after the 1 mth mark.
With my dd, I let her nap anywhere she fell asleep, the swing, the bouncy chair, etc. I eventually put her into her crib around the 4/5 mth mark and her naps eventually lengthened on there own around the 5/6 mth mark.
With my ds, I thought I would try and help him extend his naps. I tried for a month, patting and shushing until my wrists were tired. I stayed home for 2 weeks solid, and didn't extend his naps once.
Although many people have had success with w2s and other techniques, I just didn't have anymore time or energy to invest in trying to extend my ds naps.
For naptime, I turn on some classical music, place him in his crib, give him his stuffed dog, soother and taggie blanket. He generally goes to sleep w/i 5 mins. Half the time he spits out his soother in exchange for his thumb. I am carefull not to put him in bed before 2hrs and not to leave him awake anymore than 2.5 hrs.
Here is the good part For the last week or two my ds has been having one long nap a day. I really do believe that most babies will naturally adjust on their own. I think that if you have the time and the energy, you can help them along, but if you're like me, you just have to wait.
I am a big bw fan, and have all of the books, but if you want to know more about the biology of sleep, Healthy sleep habits, happy baby, by Mark Wiessbluth is good. Although, I don't feel that his philosophy on cio is appropriate for most cir!@!stances. (I will admit that I have let my dd cio, when she is trying to manipulate me into sitting with her while she sleeps, or as a stall technique)
Also, for the last week, my ds has been skipping the 5 am feed. Sometimes he doesn't wake up at all, and sometimes I have to give him his soother. But he now sleeps from bedtime, 6 or 6:30 pm to 7:00am
I hope whatever you try, you have success!
