Meth Addiction?

My husbands ex wife has had a baby that was born addicted to meth. My husband has 2 children by her(not the baby she just had) and she lost the baby. Do you think she will lose my 2 stepchildren also. My husband has custody of the children she only gets them every other weekend. But we had recieved a call from DCS and they told us to not let her have the children without supervision by my husband or her mother.
