Employment Based Greencard

I am on F1 Visa and my 6 year old is on F2. He has CHIP through the State of Maryland which I still pay a subsidized premium based on my income.The State deemed him eligible because he is a child and lawfully present. Even though I told them he is a non immigrant not qualified for public benefits, they told me the rule was change to include any lawfully present child regardless of immigration status. As long as he had an active I-20 he was eligible.

The public charge rule did state that CHIP is not among the designated benefits used to determine public charge, and also kids under age 21 who receive medicaid are exempted. Do you think this will affect my son and I ? I am about to file for adjustment of status. Also, I have a 3 year old who is a citizen and is a beneficiary of Child Care subsidy, this was not stated in the public charge rule, but when filling the new form to determine public charge inadmissibility, should I state these benefits(CHIP & Child Care Subsidy) even though they aren't listed on the form as part of public charge determination? They just started receiving it this January and want to be sure it will nit cause any problem, if it will, I can dis-enroll them since we haven't reached the months of receiving the befits.
