Is this the end of her naps?!

For the past 2 weeks, naps have been pretty much out the window. Looking back I realise that Meera only takes a nap like once in every 3-4 days. Most days she's fine without it but I can tell she needs to go down a bit earlier at night. I have dreaded this milestone for the past year since it's the only time of the day that I can do stuff freely. A lot of books seems to indicate that kids generally stop napping around age 4 so I guess it's about time. For now, I still put her to bed and tell her that she needs to rest even if she can't sleep. So far she's willing to just stay in her bed until I ring the bell so at least she gets some down time.
