I have two sons Wolf(almost 5) and Bear (2.5).
Wolf is probably HG and is currently working mostly at a late 2nd grade level and is starting a public school Independent Study program in the K-1 class and will officially be in 1st by the semester. He LOVES cars and books and is currently very into animals (predation, what makes them different, pretty much anything animal related). He is outgoing and ACTIVE and moody.
Bear is the intense baby with sensitivity and overexcitability issues. He had HORRIBLE screaming tantrums several times a day that lasted for over 1/2 hour from the time he was a couple of months old, but chiropractic seems to be helping surprisingly enough. He is extremely shy, but loves music and dancing and is also VERY active. He is a clown at home. He is very physically and verbally advanced, but we're not exactly certain where he is going giftedness-wise.
