Exactly. I remember reading in an introductory linguistics book (Fromkin's, I believe) that a linguist once conducted an experiment with his child. The kid kept saying "I want other one spoon!" or something similar. The linguist was able to get the kid to say "another spoon" perfectly, but then when he told the kid to say it all the kid went right back to "I want other one spoon". He just hadn't intuited all the rules yet. Basically, L1 acquisition is just that -- acquisition; it's not really learning in the sense we think of it in terms of L2 and other subjects (though, of course, learning the standard at school is an entirely different animal).
