THANK YOU! As I was reading these posts all I could think was "seriously"? At least I see one person here has some sense about step parents. "5BA"The only reason that someone would be upset about thier child calling some one else "mom" or "dad" is if they were not a prize parent""5C4...asitsashayduhstated, is totally incorrect! It's also incorrect to say it's out of jealousy, immaturity or childish if you don't know the situation, everyone is different! Those are your opinions, not everyone had a grand old time with steps or with the way the person BECAME a step parent. Lystra (above)hit the nail on the head when she said "5BA"It matter how the people met. If the new stepparent came in when there parents were still married then no.""5C4 She is absolutely right! All scenarios are not loving ones. When a woman KNOWS a man has a family and continues to communicate and have lunches at work, calls his cell, and moves in on a married man and break up a family-then NO WAY are the children going to want, or would I want, them to be calling her Mom! She IS NOT their mother she is a woman Dad left his family for and married=step parent that is it! After awhile the kids may accept her as "dad's wife", but she has a name and it is not Mom, they HAVE a Mom and no other woman will be their mom. Plain and simple. Now you may say jealous, immature or what have you, but as I said...that is YOUR opinion due to the fact your scenarios were different.
