Thanks I know that's the case. He started out small, and people think he is still 2 until they hear him speak. I have a strong feeling he will end up watching over his older brother. The hiding behind a door is familiar, both mine would talk and walk in front of mirror in secret for a long time before they were confident to show us. My first we were told he might be downs syndrome we refused amnio he had 6 knots in his cord and was oxy deprived for a long time. My second had 3 or 4 knots also and was deprived also. This seems pretty common in our family though!
