Some people are talking about the 'terrible two'. You can guess from the name what it means...
With my big boy, we have not noticed this at all, and he was a great child at that time. Although we are currently within a 'fucking five' period at the moment, he is still the great child he always was :)
:D 'fucking five' LOL
You are very lucky, if he has a great behavior! My Melissa is very smart girl(word of mother) but she is nimble and fearless
Oh then you must be very careful in order not to have her hearing herself. That sounds very like my second boy :)
