Glad to hear you are making progress as well. We are definitely on the mend w/ our short naps and early wake ups, but they still do rear their ugly head occasionally. It seems like most days we have averaged about 1h 40m for naps. Some days up to 2 1/2 hours, and a handful of days that we get as little as 1h 10m (those are NOT good days!!). I'm okay with anything an hour and a 1/2 or longer. It's shorter than that when it seems to cause havoc and make for early nights/early wake ups.
I have always thought he was on the touchy side, but got further proof of that yesterday. We went to visit a friend who lives over an hour away. This meant that he would not get his nap until the car ride home. His nap was an hour and a 1/2 later than it should be. He slept the entire hour and fifteen minutes home and was a BEAR the rest of the day. Put him to bed early and he cried and cried in an overtired mess. Finally got him resettled and he was up by 5:35 this morning! the day before he slept till SEVEN!! ONE day without perfect timing and it really threw him off that much. It's crazy! I'm trying to get him back on track today. Fingers crossed!
