Health care for 15 year old

My company no longer covers family coverage ... if i keep my child on it will cost me 150 a week for 1 child. that is 600 from my household income i cannot afford ... any suggestions. PS not elligible for healthy kids or MI child. I can get individual but i must be covered.. my employer still covers me so this is not an option. my 18 year old qualifies as a student and under medicaid. because they go by his own income. I am confused how health care reform helped? and is there a individual plan that covers kids only .
