He needs to say "No" to buying extras--unless it is medical bills.
As for not getting to claim him on your taxes, well, unless he what he pays for in child support pays for more than half of the cost it takes to support him,(which includes half her rent, half her car payment, half of the electric, food, cable, phone, gas, etc) he does not have the right to claim him as she is paying for more than half the cost to support him.
This seems like it is more of an issue you have with your husband than it does with the bio mom and the child support your DH pays. If he has a problem with her planning thing on your weekends, or with the travel arrangement, he should go to court and get it changed. If he chooses not to, it's not the bio mother's fault, it's your DH that is at fault.
It seem like the two of you really need to talk. Does he realize how tight the finances are due to his behavior?
