The word "put up" was used several times in this episode, and this scene is where they enter a room of new-born babies in hospital and a doctor said like this, and "put up" was translated to "waiting". Is it correct?
- This is where we keep babies that have been abandoned
or are being put up for adoption.
If something is waiting for something, it suggests to me that it chooses whether to wait. So, as FF said, they're waiting to be adopted - the mother 'puts them up' for adoption when she says they can be made available to adoption agencies.
