Sebastian is only three months old. My son has never been with Sebastian alone so I would have to say no he has never hurt him, they used to play around together so good, my son would play fetch with him and they used to chase each other but now he just barks and growls at him . I have three other kids that are older and do not need me as much as my two year old and Sebastian doesn't bark or growl at them, just the baby. The odd thing is if Sebastian is in my lap when I am holding him and I take my son's hand and try and pet him he won't growl.
