tell them that you understand that they are having a hard time at home. tell them if they want to talk and share their feelings with you they can or maybe they can draw some pictures of how they feel(sometimes thats easier for little ones). just let them know that you are there for them and that you, and their mommy and daddy still care very much for them and that what is going on at home is not their fault. but make sure they understand that naughty behavior will not be tolerated and that you are still using the same consistant discilpline and routines as before. right now they need lots of love and costistancy...more than ever before, because their entire home life is in an uproar. if they start the "i wanna go home" bit again tell them...not until mommy/ daddy comes and get you, they are at work. continue to talk to their mom, and ask if it would be OK if they called her at work occasionally, if they start getting really upset...some mommy tlc over the phone might help some.
