Of course Will at 5 doesn't nap. And hasn't for well over a year or so.
Madelyn is just over 3 and she is starting not to nap more and more. Up until about a month ago we would put her down for a nap around 1 and she would nap 1.5-2 hours and on a rare occasions a bit longer. In the last month we have changed nothing but she often just does not fall asleep. I am still holding onto hope that she may continue napping once it warms up and we can get outside more and burn up more energy but I am not sure this will happen. Of course losing her nap has some advantages, going out in the afternoon is easier and by bedtime she is exhausted so crashes quickly. Also since her and Abigail's naps are opposite right now it is nice to have some time between 10-4 where you are not eating lunch or having a child napping. But there are still days when she really needs her nap or Mom really needs her to nap.
Abigail recently switched from 3 to 2 naps. I think of all 3 kids she transitioned the easiest probably because we are often on the go so we were really just too busy to notice she stopped having a short supper time nap. When we are home Abigail likes to nap around 10-11ish and then again about 230-4ish. But she is fairly flexible especially with her morning nap!
Needless to say there are not many breaks in our house, however I do take advantage of some quiet time and let Will and if she does nap Madelyn watch some tv for a while in the afternoon, we all need the break for a few minutes each day!
