Four weeks. If the child is not transitioned with no crying (or mostly no crying) within 4 weeks then I start to think about terminating. Usually if a kid is still heavily crying at the end of week 2 I start to chat with the parents about what they are REALLY doing at home, example - picking them up a lot, responding to every whimper etc. And then I tell the to cut it out because it is hampering his progress in group care and they usually get it and get on board.
