I suggest... in a calm "willing to work with" voice, explain your concern with many children in a household that the Yorkies may just be "underfoot" a whole lot, and that you are willing to take them if he finds that they are just too much with such a busy household. ................ then wait....... you may be surprised.
You can also express how much you will miss seeing them and because they will be so far away , if you could pick them up for a week now and then.
Try the "Kill with kindness" effort first. Sometimes it really helps .... plus put the ball in HIS court.
If that don't work..... maybe his new wife may be more cooperative... Just don't freak out and start yelling/crying/etc...... it definitely would be a negative. Kind, not demanding words. (You really don't have much more that you could do..... because he has had the dogs for awhile already)
Good luck! Will be keeping you in my thoughts.
