Hi, congrats to the new baby!! She is adorable
Try not to worry about her low weight. Yorkies have different spurts of growing. She may gain fast or stay very tiny. I have two yorkie girls myself. Trixie wasn't even 1 lb. at 12 weeks of age and now at 14 months she is just hitting 5 lbs. My other yorkie is Pia and she is very tiny. She's 2 lbs. and 1 yr. 7 mths old. Both babies are extrememly healthy. I give Pia 2-3 licks of nutrical every day just to be safe. I had no idea Pia was going to be so small. I was a nervous wreck at first with her. Trixie was the smallest dog I had ever seen so when I got Pia I was beyond amazed. I got Pia when she was almost 1 yr old and she only weighed 1.8 at that time so I do know how you feel. She may have weighed a few more ounces then Trixie did but Trixie was 12 weeks and Pia was 1 yr. Pia's frame is so tiny and that makes such a difference in my opinion. Your baby will more then likely double that weight and maybe a little more. Try not to worry!! I bet everyone on here can relate to your feelings of having such a small dog for the first time. Pia at 2 lbs. has grown on me and the nerves have gone away. I promise you will get used to her size. Yorkies may be tiny whether 2 lbs. or 10 but they are tough little buggers. You are going to have so much fun with her. Can't wait to see future pics!!
