Hi there and welcome to YT!!! Your gonna love it here

I have two yorkie girls and a pekingese. My one yorkie is very small (2 lbs. fullgrown) The best thing I can recommend is to always make sure your baby is eating enough. It would be a good idea to buy some nutrical from petsmart or petco. When their so small you really have to watch their sugar level dropping. This is known as hypoglycemia. Heres a link that I suggest you read

I'm not trying to scare you but its something you definately need to know about. Good Luck with your new baby!!
