I'd give it a full two weeks of full days and than see if that helps. Transitioning, being ill and being pt will all make a transition period less than ideal.

In the meantime, keep doing what you would normally do. Stick to your routine as much as possible and hopefully she will become adjusted. Offer comfort and cuddles from time to time but don't let it become a habit. The more comfortable she is with you and your dc, the sooner she will settle in Good luck!!
