Naptime - AAARRGGHH!!

Naptime was always so precise when Kaden was younger, he took one nap in the morning and one in the afternoon. The one in the morning was 45 minutes to one hour and the one in the afternoon was 2-3 hours. Ohhh I miss those days, pure bliss. Now he seems to change his mind weekly. Lately he wants his nap about 45 minutes before lunch and if he falls asleep then he wakes up after an hour hungry. So now I am in rush mode and it is hard. On Mondays and Wed. Bailee gets out of preschool at 11:45, this is also the exact time Alexis calls me daily to tell me what she ate so we can put it in her insulin pump. So I have to pick Bailee up from school, keep Kaden awake on the way to and from preschool (if he falls asleep the afternoon is a nightmare), talk and pay attention to Alexis, and get lunch into Kaden all in about a 45 minute time frame. The following is the result. The first picture was taken last week and the second a few weeks ago when he was going thru a similar stage. Is it too much to ask that my kids coordinate nap time with what is convienent for me?
