I've mentioned earlier in my blog that I've never heard my stepson actually call me his stepmom before. When kids or adults have referred to me as his mom in front of him, he adamantly sets them straight, each time forcefully saying, "SHE'S NOT MY MOM!" But, there has never been further clarification on who or what I am until yesterday.
When I picked up SS from his winter day camp, the camp counselor said, "M, your mom is here to pick you up." He immediately responded with a gentler, "That's not my mom." And then..."She's my stepmom." Ahh! Music to my ears. A complete outsider no more.
