Amend child support order?

My ex who right now has every other weekend with our son just went to court to amend child support order after it being ruled by judge starting June 1 st 2011 to start paying.He stood up in court and also provided a financial affidavit that stated he had a job and now he does not but just acquired a roomate and a pitbull,he can afford to feed his dog but not his kid.Should I object?I fear if I do he will have time before our next case to cover his butt,which is at the end of the month.Or should I just wait to court to provide my evidence?
