Just to add from one of those early reading angst parents... Having one kid in middle school and a youngster coming up...reading level seems to be an indicator when entering school and can make life a bit easier that one is not a pushy parent if the child can clearly show early reading......
I don't hothouse but I do feel an urgency that the little one can have a way of showing her ability that is easily identifieable by who ever I need it to be identified by when the time comes....
My middle schooler's SAT scores have talked many more miles and opened up many more doors than anything else has from the school personnel. They understood those numbers.
I think early reading is similar...it is something that the elementary teachers understand as advanced...more so than say an IQ level and what that really means.
Sorry if this is repetitive, just not sure how clearly it comes across what I am trying to say.
