Have you tried the heart beat thing? I had my yorkie at 5.5 wks because her mom got real sick, and I just kept her with me and on the heart beat pillow they had then in her crate and with lots of fuzzy animals, and she was okay in about a week.
I'd put Tucker's crate or bed near/but not where he can get to her until she sees him as friend and gets used to all the new smells etc, and just keep her with you as much as possible. It was a week of intensive "me" for mine, then she got to where exploring was a priority, and playing, and then she was okay. Hope this helps.
