Frances: Re: OTC.... a problem is that it depends on what she is taking... there is NO blanket statement. Possible answers: . check with a board certified lactation consultant or a bf advocate with the resourses ( hale, briggs) to look the information up.

They are covering themself from lawsuit.... Patricia
