A note on sizing: Emma was about 5 lbs when she got spayed, and Milli was barely 4 lbs, and they both wore the 0-3 month onesies. The trick is that you have to wash and dry them a couple times before they wear them so they shrink down to the size they're going to be. Gerber brand onesies fit smaller than the WalMart brand did....Emma now weighs 6 lbs and the WalMart brand onesies still fit her, while Milli was swimming in those, and had to wear the Gerber brand onesies. I think Gerber also makes premie sizes, so if you have a yorkie less than about 3 lbs I would recommend getting those.  
They come in all colors and patterns-so check 'em out and get some blue ones or some with cars or frogs on them for your little yorkie boy!
