Breastfeeding social reactions in the English-speaking world. It is possible for a mother to continue breastfeeding an older sibling while also breastfeeding a new baby; this is called "tandem nursing". During the late stages of pregnancy, the milk changes to colostrum. While some children continue to breastfeed even with this change, others may wean. Most mothers can produce enough milk for tandem nursing, but the new baby should be nursed first for at least the first few days after delivery to ensure that it receives enough colostrum. Breastfeeding triplets or larger broods is a challenge given babies' varying appetites. Breasts can
Positive form a unique connection preserving the Hermitian structure and satisfying This connection is called "the Chern connection". The curvature formula_16 of a Chern connection is always a purely imaginary (1,1)-form. A line bundle "L" is called "positive" if is a positive definite (1,1)-form. The Kodaira embedding theorem claims that a positive line bundle is ample, and conversely, any ample line bundle admits a Hermitian metric with formula_17 positive. Positive (1,1)-forms on "M" form a convex cone. When "M" is a compact complex surface, formula_19, this cone is self-dual, with respect to the Poincaré pairing :formula_20 For "(p, p)"-forms, where formula_21, there
