Hi, I’m going through baptism records, searching for ancestors and ran Into this one and have seen others with “expuesto en casa de..”, what does expuesto mean?

Hi, I’m going through baptism records, searching for ancestors and ran Into this one and have seen others with “expuesto en casa de..”, what does expuesto mean? I used translate but does not make sense. Does it mean the child was abandoned at this persons house or can this be his illegitimate child ? This one caught my attention because I have Hernandez Gamiño in my family tree.
