Karen,

I have had the misfortune to have had to work with this type situation before.
In each and every case there were circumstances that the mother did not relay
to us which made the baby's removal from the family necessary.  My
recommendation is to tread lightly and continue to gather information.

You, mother or her attorney can contact La Leche League.  They have a
Professional Liason department that has vast stores of legal information.  Her
attorney will also be able to gather the references needed.  There are LLLLs
and IBCLCs who will testify if need be but will undoubtedly need to be
assuared that the baby is not in danger of any kind.

Good luck!

Linda
