Recently as well as in the past, my kids have had to correct coaches, teachers and others who have been mistakenly told that their stepmom is their Mother.  I personally don't know if it's my ex-husband filling out paperwork with his wife's name listed as my children's Mother or if it's his wife doing it, but my kids are REALLY starting to be bothered by it. 
My son will be making his confirmation soon through the church that he goes to with his Father. My son was very upset when he found his confirmation form filled out with his stepmom's name down as his MOTHER. 
So I fired off yet another email to his Father:
Dear (insert ex-husbands name),
 
Jacob expressed some anger to me about his stepmom's name being listed as his "Mother" on his Sacrament of Confirmation form.
 
In the past, the same offense has been committed when your wife's name was listed as the "Mother" on one of Sara's soccer rosters. I have had to explain now, to both of the kids, that an inaccurate name written down where my name should go, will never change the fact that I am their Mother. I've also tried to get them to discuss their dissatisfaction about this subject to you, but again, they are unable or unwilling to bring these matters to your attention.
 
With Jacob now struggling amidst this inaccuracy, I refuse to offer an excuse to Jake for your reasoning behind lying, on a religious document no less. Dishonesty seems to taint the Sacrament of Confirmation.
I can only assume you are simply unaware of how this bothers them.
 
Regards,
Terri
Immediately following the sending of the email, my son Jacob found the confirmation form in his room at his Dad's with BOTH the Mother AND Father names NOW ERASED. I'm not sure which genious over there at his Dad's thought that that was the appropriate way to handle this. So immature! Somebody at his Dad's (either Dad or stepmom) appears to be actually MAD at my son, because my son is mad about the WRONG name being listed as his Mother's? Honestly, I am disgusted with the disrespect that my ex & his wife display for me and my children.
