How many hours is she sleeping at night? Babies this age need around 15 hours of sleep a night/day. This is however an average and your baby may sleep more or less depending on her needs. My girls always needed more than average amounts of sleep. For example, my 16 month old SHOULD need 11 hours of sleep at night and only one 2 1/2 hour nap. Well she sleeps 12 hours a night and takes two 2 hour plus naps a day. I guess what I am saying is each baby is different. If she is sleeping 8-12 hours a night and getting a lot of mini naps I wouldn't worry. As far as where she sleeps, I wouldn't worry about that either as long as she IS napping at all during the day. Read what is out there and follow your instincts. If your baby is alert, eating well, and growing well (growth hormones are produced at their highest concentrations during sleep), then I would rest easy.
My girls didn't even see the inside of a crib until were 3-5 months old, I co-sleep. The took naps where ever they were at the time. I kept my youngest (now 16 months) in her carrier until she out grew it so I could carry her around the house with me. This was to protect her from her older sister LOL, they are only 18 months apart. That is where she napped most of the time, that or the chair and a 1/2 when her sister was asleep.
With this being your first little one, there is no real reason to worry about where she sleeps. There were times when my oldest would just fall asleep on her blanket in the middle of the floor, I would just leave her there and go do something quite. This was of course after she was older and mobile :o).
As far as sleep scheduling goes, I let my kids set there own. Once they have them set, usually at the age of 9 months to a year, I try to loosely adhere to it, watching for their sleepy signals. They are usually dead on with 30 mins to an hour. Before 9 months or so I don't "Really" control their schedule at all. Hope this helps.
