I have to say that I feel that she is much too old to be swaddling - they usually stop around 3 months of age. Especially at 6 months - they are moving around more and that constriction can be quite frustrating and may be causing her lack of sleep. If you stop swaddling it might take a couple of nights for her to get used to it but it will be better. At her age - babies usually should be taking 2 naps a day. Do you have a nighttime routine? Put her to bed at the same time every night and have some kind of routine - (i.e. bath, read book, etc...). Also, try to have the daycare lay her down for her naps at the same time everyday. Consistency and routine are ideal for babies. Good luck.
