My son is the same way. He is 13 months now and has been this way since about 6 months. When he was an infant he slept all the time...he had a hard time feeding for a month or so after he was born because he just couldn't stay awake. Now..it's quite the opposite.
He also will bang toys against his head and sometimes he will even bang his head on the wall!!!!!!! I had a fit. He is constantly going and going and going...like the energizor bunny! NO JOKE. He never calms down. He doesn't like to cuddle unless he is really tired. I too, am worried about hyperactivity but I brought this up to his dr. and he told me that at this age it's just to early to diagnose and way to early to medicate. I don't even know if I would medicate him if in fact, when he is older he is diagnosed w/ some kind of hyperactivity disorder. I have heard some horror stories. My son does the exact same thing "lil'momma"...if I'm doing something or reading something that he wants he will stop at NOTHING to get it and if he does he just sits there and trys to tear it apart.
What bothers me the most is that he is so strong for his age. He has such a temper! When he starts getting really hyper...I'll just take him and sit him on my lap and I have to use all of my strength to hold him. He is stronger than my mother, my grandmother, and me.
I have often wondered what this might mean and many times I have just dismissed it to normal 1 year old behaivior. I think a lot of it is... however, some of it does throw off read flags in my head. He is just so determined to get what he wants and do what he wants!!!!!!
It must sound like he is the worst little child but he isn't really...like you said "lilmomma" my son is a really happy baby most of the time and he is a real joy in my life...he's just a hand full sometimes
