She's just 4 years of age and already grown breast of the size of a matured teenager.
According to 'Shari Nethersole' a physician at
Children’s Hospital, Boston, and an instructor in Pediatrics at Harvard Medical
School.
The onset of breast development in girls less than 8 years of age may be
the first sign of precocious puberty or more likely a condition
referred to as benign premature thelarche. Benign thelarche is most
commonly seen in girls who are under 2 or older than 6 years of age. In
those girls under 2 years, breast tissue is thought to be a consequence
of infant gonadotropin secretion and ovarian hormone production. History
and physical findings that support benign development include presence
of breast tissue since birth, waxing and waning size of breast
development, absence of other pubertal signs, and no evidence of linear
growth acceleration. Additionally, benign thelarche in girls under two
years rarely exceeds Tanner stage II development.
