Your babies are just beautiful. They look like the Biewer Yorkies. At this age you can also give them some baby food meat and baby food meat sticks. They can eat baby food cereal mixed with some applesauce or pears. Good luck with those babies.
I have two Yorkie girls that are 1st cousins and are only 6 weeks apart in age. I would never have only one now. They were quite a bit of work for the first year and half, but looking back, that was the best time of all!!
