Hi M., I don't have any step children, but my oldest son has a stepdad, and a stepmom with his biological dad. My husband came into our lives when my son was 5, he is now 14. His stepmom came into his life when he was 3. I have three other boys with my husband, and my ex has three other kids with his wife. My husband is my oldest dad in everyway except geneticly. He does everything that a father is supposed to do for a son, and he calls him his son, not his step son. Now the case is not the same with his stepmom. Even though he was here before her, she knew she was getting involved with a man with a child. She has never treated him as her own and he tells me that she hates him. As he gets older she thankfully is getting nicer to him. You didn't say anything about their mom that gave birth to them, so I don't know what that situation is. I can tell you as a mom of a son with a step mom, it makes me very anger that she does not love him like her own. He was a little boy when they met, she has watched him grow, I thought it would change when she had her own kids,and it has, but it got worse before it got better. Also my son knows that his stepdad is his dad in everyway. We have talked about it now that he is a teenager. He knows that my husband loves him and would do anything for him (and does). His "real" dad is more of his buddy, he takes no responsibility for any of the "tough" stuff it takes to raise a kid. Also, when I hear people "correct" others to the fact that the child is a step child, it makes my heart ache. I've heard this said at my sons school by another mother, and it makes me so anger that she felt the need to say that. It made me feel that she didn't love him the same as her own!! And if I felt it I'm sure the boy does too!! Like I said my son knows how his step mom feels about him.
Don't worry about what anyone else thinks or says!! You are doing the right thing!! Your husband knows it, your girls know it, your sons know it, and you should know it too!! All those people that say those ignorant statements to you, would want someone like you in their childs life if they were in this situation. You should be proud of your love for those kids. Don't call them anything but your daughters, because that is what they are!!!!!!!!!
