sounds like you are doing everything you can. yorkies are just like kids, they want you around, difficult to leave a kid @ daycare but while your leaving they cry, once you leave they are fine. your pup is very young & tiny, i am not an expert by any means, but as long as you leave the essentials & are not gone too too long the pup will be fine. probably a lot harder on you than him or her. good luck, you sound like an awesome parent. best of luck
