How can I be a better stepmom?

I am a stepmom.THIS KID IS 5!!!!!!!! This little boy is going thru a lot right now..and your attitude towards him is not helping. He probably thinks if he stands up for himself he is going to get in trouble. ANd admit it...if your son whined to you that step brother was being mean..you would get onto the stepkid...RIGHT!! You need to start treating those kids as equals. IF your son picks on him...then your son goes in the corner...not the stepson! Once he realizes you are being fair(and your not now!!) then maybe he will stand up for himself. You dont need to "baby" him..but he may need more encouragement than the other kids right now. GOODLUCK!
