I just saw your question, and already posted the answer to Bobbym. I'm hoping to drum up some prayer for the little ones. I think the main thing to pray for is that the government adopts a serious and realistic plan for the poor and that will stop a lot of the abandonment.
And that there will be more advertising of the conditions the babies and children have to grow up in in these institutions.
Only the Lord can change hearts and all we can do for that is to pray for a miracle.
