Talking with Toddlers

This video was recorded about 10pm tonight following a 45 minute "play" session with some flash cards and 10 minutes of Coloring time. Alex did not appear interested in play time tonight like he usually is. My mother in law was staying with us and I'm not certain if his playtime mood was changed by that or not but I made the mistake of not setting my expectations with her before the play time and I think that confused things. The video below is about 2 minutes long and shows how Alex sometimes communicates with us. Not many breaks exist in his sounds like usual whenever he is tired. I cannot tell for sure if this is a form of "whining" or if he really thinks he is talking. He is looking at both his grandma and I while he was "talking".
