Yes, Yorkies can be
good with children , but due to their small size,
kids need to be taught to handle them gently and avoid rough play. Yorkies are terriers, so despite their adorable, tiny exterior (of which they are totally unaware), their stubborn temperament can sometimes make them a little defensive towards the rough manner in which young kids may handle dogs.
As with any breed, it is recommended that your child is always supervised when interacting with your Yorkshire Terrier to keep both the child and dog safe. Pet parents also need to provide their Yorkies with proper socialization and training to behave well around children.
