Solution: Explore Kinder goats, a cross between Nigerian Dwarf (or Pygmy) and Nubian goats.
Explanation: Kinders were developed to combine the high butterfat of miniatures with the higher volume and dual-purpose (meat) qualities of Nubians, while maintaining a manageable mid-size (larger than Nigerian Dwarf but smaller than Nubian). They are known for good milk production (volume and components) and longer lactations.
Notes: Less common than Nigerian Dwarfs but gaining popularity. Classified as a 'small' rather than 'miniature' breed by some registries.
