Shan, we are currently going through the same thing with Aricyn. He had a morning sleep today for about 2 hours (9.30 - 11.30) and now is STILL up after we tried putting him down for naps at 2.30 (his usual time), 3.30 and just now again. We are going to try again at 5, he is really tired, and he is also sick, so not sure what is happening. It has been suggested that he is getting ready to go for the one nap during the day (the long midday sleep) but I think he still needs his morning one!!!! Just wanted to let you know that you are not alone!! Oh, but if nothing else helps Aricyn, i throw a blanket over his head and that usually sends him off to sleep. hard when they are standing though!! sorry for not much help, but I'm struggling with you!!!
