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
Genus of a quadratic form so in this case all genera contain the same number of classes of forms. Genus of a quadratic form In mathematics, the genus is a classification of quadratic forms and lattices over the ring of integers. An integral quadratic form is a quadratic form on Z, or equivalently a free Z-module of finite rank. Two such forms are in the same "genus" if they are equivalent over the local rings Z for each prime "p" and also equivalent over R. Equivalent forms are in the same genus, but the converse does not hold. For example, "x" + 82"y" and 2"x"
