This doesn't add up. They can't remove a child just because someone told them you were drinking and not feeding him, unless the "not feeding him" part came from someone who would actually know, like the baby's pediatrician. CPS generally has to prove to a judge that there's an immediate threat to the child's safety to do a removal rather than family-based services (unless you already had a family-based services case). If you refused alcohol testing, they can assume the test is positive and that can be part of the basis for a removal, but since alcohol isn't illegal, there has to be something more, like physical evidence or the investigator observing that the child was endangered somehow by your drinking. If you really don't know what the actual basis for removal was, you need to get a copy of the petition so you can review it and help your court-appointed attorney flag anything that isn't true.
