Dear doctor,
I have a 5 year old son, he is very loving and affectionate with every one including his 6 month old brother always wanting to help and giving him kisses and hugs every chance he gets. he loves super hereos batman spiderman wolverine ect so naturally he walks around most of the time convinced he is a ninja hiding behind things fighting with pillows and what not . with that being said the other day in the car he said to me i could kill all the baby's and immidiatley i was panicked by the statement, and i explained to him that , that kind of behavior is wrong and saying things like that are very very wrong and reminded him his little brother is a baby and he began to cry saying he could never hurt his brother, saying he was sorry. should i be concerned ? because honestly the statement really scared me
