I definately notice how excited my daughter feels when I teach her. I really agree that we are our child's first teacher. Not to mention, it is such a great bonding experience.
One thing that I like already about SM is that it allows me to learn at the same time and after I learn, I teach my daughter. I am probably the best teacher she'll have. Definately, something that I'll remember fondly when my daughter is all grown up.
My youngest has pressed the keys since he was around 8 months old. He has progressed from banging the keys. Since then, from time to time, I take his hand and play the five finger exercise for him. Starting 11 months or so he has been more gentle with the piano and also has understood that a key has to be pressed with one finger.
Sometimes, when his right hand is on the table or on piano or on other surface, he seems he is doing black cat white cat exercise. Just seems, remember. I think it's more like his need to develop finger mobility.
I am very curious at what age will he be able to play on his own. I am amazed how fast he's learning. He's taking big pages with a solfege symbol on it and singing what he knows from solfege trying to sing the note
