My 2 daughters, now ages 4 and 6, were born with my 4lb yorkie who died a few months ago at the age of 17. We now have a 8 month old and 3 month old yorkie pups who are 3.5lbs and 2lbs. My girls know the rules: no jumping/running when pups are around and they must sit on their bums when holding them (no carrying allowed). When their friends are here the pups go in their bedroom for safety. We also have a ex pen. My girls have always been excellent with the dogs and yours can be too. Just always supervise in the beginning to remind them. Good luck and welcome to the world of yorkies
