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
Sesquilinear form of a complex Hermitian form is a Hermitian matrix. A complex Hermitian form applied to a single vector is always real. One can show that a complex sesquilinear form is Hermitian iff the associated quadratic form is real for all . A complex skew-Hermitian form (also called an antisymmetric sesquilinear form), is a complex sesquilinear form such that Every complex skew-Hermitian form can be written as times a Hermitian form. The matrix representation of a complex skew-Hermitian form is a skew-Hermitian matrix. A complex skew-Hermitian form applied to a single vector is always pure imaginary.
