Lily, what a sweet name for a little mite.
I am sorry, no criticism was intended,please do not take it personally.

Just a heads up for the safety of all pups, other new yorkie owners may read this thread, they should know puppies should stay with the mother and litter mates until they are at least 12 weeks old. In this time the mother is teaching her babies many things, most importantly bite inhibition, litter mates play a big part in this, they teach each other to bite with a soft mouth, to be social. Now that job is up to you.

If your vet has cleared Lily as a healthy puppy that's a good thing. Just make sure there is always kibble available for her, there is no such thing a a over weight puppy, so free feeding is suggested, they burn a lot of calories because this is a very active breed as you know since you have other yorkies. And in having other yorkies you know the importance of keeping Nutri-cal on hand in case of hypoglycemia.
Your concern was Lily choking on Kibble being she is so tiny, you haven't said if she eats fast and wolfs down her food or if she chews her kibble.
