I also have a 10 month old... and I just read an article about this, so I'll try to paraphrase.
They say that babies this age are not throwing tantrums, they're just not capable of trying to manipulate mom or dad this way yet. Supposedly a child of this age gets his self-value from having his needs met. And all wants are needs to them, as in needing to reach that toy, needing to get out of this carseat, etc.
The only advice the article mentioned was to try and meet as many of their needs/wants as physically possible. Obviously you can't get them out of a carseat while driving, etc., but help them reach something, pick them up, etc. And supposedly they will grow out of this type of behavior, and then I supposed we're in for the true tantrum behavior! :roll: :wink:
