my dd gave up her cat nap at 6 mos, so it might work. That said, does she really go down for a nap at 9 after only 1.5 hrs of A time? At that age, my dd got up at 7:30 and didn't go down for her am nap until almost 10. I could give you our sample routine, but the nap times would be way off what the nursery does. If she's taking those 1.5 hr naps at those times, she probably does need that extra cat nap, because she just can't make it from 2 to bedtime. Does she catnap at the nursery? If she does, and it's working, then I'd keep it. If she's not taking those naps at nursery, then maybe let's try to tweak the routine a bit.
