I am in tears....that last picture is precious!! My Livi just had her first litter and also my first Yorkie baby, too.
Her litter was full of heartache (lost puppies after trying so hard to keep them alive) and now we only have one. We are BEYOND attached to him so I just know that we are going to have a hard time letting him go. Livi loves her baby like your fur girl does so I don't look forward to how she will respond.
I am sorry that this was so difficult!
