When my son was little and if I remember right he usually had two naps a day. I remember for sure that he always took a early nap not too long after breakfast and then later on in the afternoon he would have a nap. Brandon could be very cranky if he didn't get his naps in. I'm not for sure at what age he switched to just one nap a day but it did eventually happen. I also remember that you never wanted to wake him from a nap because he would be super cranky for awhile if you had to wake him for some reason.
