Need sleep stat!

So, lately Tyler has decided he doesn't want to sleep at night. For the past two weeks, the longest stretch of sleep Tyler has gotten in a row has been 3 hours. Ugh! He has a cold right now which doesn't help. Besides that, we're not sure what is going on. I even took him to the doctor today thinking maybe he had an ear infection. No such luck. We are going to chalk it up to his new tricks he's recently learned...sitting on his own and pulling himself to a standing position. Once his cold passes, hopefully we'll get sleep again!
