dear C.-
my advise to you is to go for it! my son is 4 and he has been reading since 1 1/2. he can do so much more than all the children in his 4K class. he is like a little adult stuck in a kid body. unforunatley we could not afford montessori schools so he is going to public school. he has a wonderfull teacher who reconizes that he is way ahead of the class and she does her best to keep him occupied but she does have 16 others to teach. he gets bored very easily and they see it as misbehaving. my son loves to be challenged and if he is not then he tends to make up his own challenge which is seen as misbehaving. he can read,spell,write,add,subtract,knows his states,abc's,counts to 50,etc..... for show and tell he built a circuit board and made a siren for the kids. he was upset because the children were not interested in what he was doing until the siren made noise.
if you can do montessori---- more power to you! good luck!
M.
