The birth of my child is looming, and we're scared about finances. I currently don't have a job in my field, and I only make half of what I COULD be making right now. My fiance called the Child Support Agency and asked them if anything changes when he has another baby with his current Child Support payments to BM. They told him he can write a letter and explain the changes that are occurring in his life, which include the new child, and they will review it.

We are kind of excited but trying to not get our hopes up. However, a light bulb went off. Isn't this the perfect time for DF to outline all the atrocities committed by BM as well -- that add to the reasoning for us not to pay her as much child support? These are the things I think DF needs to include in his letter:

1. Right now, the child support my fiance pays covers day care for SS3, plus about $150 beyond that. BM does carry SS3 on her insurance, but she WORKS for an insurance company and DF knows for a fact that the amount she pays to cover him is only around $40/month. So she's technically getting about $100 to cover other expenses, which would be completely acceptable if she cared for SS3 a majority of the time, but -- This leads us to the next point --
2. We have him 50% of the time according to the stipulation. We have plenty of documentation that BM consistently does not care for SS3 on her weekends, but instead he stays with her parents. Therefore, she is technically NOT providing care for her child for the 50% of the time he is supposed to be in her care.
3. We have documentation of numerous days per month when BM asks us to take SS3 additional days/nights.
4. There have been 3 instances in the last year when DF has taken unpaid days off to care for his sick son, while BM has PTO she can use but refuses to use it to care for her sick child.
5. 3 times in the last year, BM has asked DF for help with paying for day care costs for the week. She promises to pay him back the next week. This equals up to $330 so far, and she refuses to pay him back for any of it.
6. In the last 6 months, BM has gotten a promotion at her job, and we are fairly certain that she now makes more money a year than DF.
7. We care for BM's daughter 2 days/nights a week, although we have no legal visitation or custody of her. We do not receive any compensation for this.
8. BM refuses to help pay for activities for SS3 to be involved in, stating that she has no money to pay for such things, even when we offer to pay half. However, she gets her hair highlighted often, tans, gets her nails done, and we she goes to the bars and drinks at least 2 nights a week (documented as often as we find out).

Does this stuff sound petty? Or is it worth including?
