Layla is 5lbs. her mom was 6 and i blieve the main male she uses is 3... There was a small girl in the litter that i believe would be around 3-4 full grown but i didn't want one that tiny. She has females that are 4lbs so if you can get in on that litter, i'm sure the size would be around the same as your two now, however i don't kow becuase i wanted one around 4-6 lbs... i got lucky and got just that
