Welcome!! My Teddie was around 3.5 pounds at 12 weeks, and he is now a little over 7 pounds at almost 20 weeks. He's not gonna be an itty baby, but I wasn't looking for him to be. This place is awesome for advice on everything, everyone is so knowledgeable and helpful here. You'll have no problems keeping your baby happy and healthy with their info. Congrats on your furbaby...
