WB! J is 3y4mths and can still nap for up to 3 hrs a day (and sleeps well at night) we are just starting to cut back the amount he sleeps but he will keep napping for a while. DD is 4y8 m and still naps every 2-3 days as well for 2 hours so it really is up to what the child needs. I find it easier for me for them TO sleep as I get a lot done but it can be a PITA if we have stuff on. Now they are older though they jus skip the nap for the day and we get them to bed a bit earlier. If she is skipping it and seems happy then you could change to a rest time? I really find that if they are up from 6-7-7 that they still do need some kind of down time even if they aren't sleeping but that's just me and others find their kids can go flat out for 12 hours with no worries!
