Stepdad bruised sons neck in play fight?

yea he is your husband but not your sons biological father. so as the mother, it is completely allowed to be concerned about the bruise, esp since its on his neck. ask your husband if you can talk to him (without the son present), then tell him how you feel and that you would like him to tone down on the rough housing. if you talk to him in a mature manner and don't yell and start fighting then there should be nothing bad between you after you talk to him. try not to lose your temper and you will do fine.
