I understand your anxiety in dealing with this issue, but the best source of information you have about this is your attorney. That person knows the details of the family, DCF's position, the requirements of the 4-year-old, the status of the other kids, etc. Since there are six children, who are obviously already split up if you have two of them, DCF wants the ideal situation, but cannot reasonably expect it to occur. Your attorney can work with DCF and with the judge to find proper and safe placements for all six kids. Work with and TRUST your attorney.

As Ms. Amarantes noted in her response, if you have an attorney you should ask him or her. You attorney should understand the details of your case and should be able to give you the advice you need. I hope you found my answer helpful.
Please consult with your attorney.
