Nursing bra

Nursing bra is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nursing bra rather than just read about it. In short: A nursing bra is a specialised brassiere that provides additional support to people who are lactating and permits comfortable breastfeeding without the need to remove the bra. This is accomplished by specially designed bra cups that include flaps which can be opened with one hand to expose the nipple.

Key takeaways

  • Nursing bra belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Nursing bra to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Nursing bra from memory before moving on to harder problems.

Reference excerpt

A nursing bra is a specialised brassiere that provides additional support to people who are lactating and permits comfortable breastfeeding without the need to remove the bra. This is accomplished by specially designed bra cups that include flaps which can be opened with one hand to expose the nipple. The flap is usually held closed with a simple clasp or hook.

Purpose A nursing bra is designed to provide quick and easy access to the breast for the purpose of breastfeeding an infant. It typically has flaps or panels that can be unclipped and folded down or to the side with one hand. Nursing bras can be worn under a variety of outer garments.

Changes during pregnancy

Measurements for an appropriate nursing bra can be performed by a lactation consultant. People can choose nursing bras with strong side and undercup support and an extra-wide back for optimal support. Nursing bras usually have up to four rows of hooks in the rear closure to allow the people to adjust their band size to a limited extent. Experts recommend a soft-cup bra made of a blend of cotton and Lycra with cups that stretch to accommodate changes in breast size. Most people who get them buy two or more nursing bras so they can alternate between them. Small-breasted people who do not usually wear a bra may choose to wear a nursing bra to support their larger breasts or simply to prevent milk from leaking onto their clothes. Pregnant people should consider buying a maternity bra as soon as their regular bras begin feeling uncomfortable or notice their breasts are changing. This is normally around the 4 months mark.

Breast sizes change A woman's breasts grow during pregnancy, usually 1 to 2 cup sizes, and potentially several cup sizes. A woman who wore a C-cup bra prior to her pregnancy may need to buy a larger bra while nursing. Once the baby is born and about 50 to 73 hours after birth, the mother will experience her breasts filling with milk (sometimes referred to as “milk coming in”) and at that point changes in the breast happen very quickly. Once lactation begins, the woman's breasts swell significantly and can feel achy, lumpy and heavy (which is referred to as engorgement).

Changes during nursing To provide proper support and fit, to facilitate nursing, and to avoid engorged breasts or other complications that prevent an infant from nursing effectively, it is important to wear nursing bras that fit well. When a woman wears a bra that is too tight, her milk supply may be reduced, and she can experience plugged milk ducts and an extremely painful infection called mastitis. Mastitis can physically and emotionally affect the mother's ability to breastfeed.

Types of nursing bras

There are an increasing variety of nursing bra designs, including softcup, underwire, seamless, and lounging styles. Some nursing bras can also serve as a sports bra, allowing a nursing parent to exercise more easily. Some outerwear like tank tops and T-shirts have nursing bras that are built into the garment, and there are also padded and plus-size nursing bras. Some experts advise against wearing an underwire nursing bra because they can restrict the flow of milk and cause mastitis. Most nursing bras have traditionally been white, but manufacturers now offer an increasing selection of colors and styles, including brown, teal, floral, and floral animal prints, and some are accessorized with lace and ribbon. Different manufacturers use different methods for fastening the flap to the cup, including squeeze, snaps, clasps and hooks. Most nursing bras are designed with cup flaps that fasten at the apex of the bra, at the point where the shoulder straps attach, allowing the mother to simply pull the top half of the cup down to facilitate access to the nipple. Other designs include flaps that fasten between the cups at the center of the bra, zippers under each cup, and a cross-over design that allows the wearer to slip their breast out. Experts recommend that before buying a nursing bra, people should try on the bra and experiment with opening the flap with one hand. Some designs utilizing stretchable fabric are suitable for smaller-breasted people, allowing them to pull the entire bra up over the breast to facilitate nursing. Experts recommend nursing bras that are stretchy, absorbent, and don't bind the breasts in any way that could interfere with milk flow. People are recommended to wear a bra that is 100 percent cotton or a cotton-Lycra blend or other stretchy synthetic. It is not necessary to wear a bra at night, although if a person's breasts leak excessively, they can wear a loose tanktop at night.

Bras and breastfeeding

Choosing a functional nursing bra is important to help the parent feel comfortable nursing in various circumstances. In some Western cultures, while nearly nude or nude breasts are displayed openly on beaches and in magazines and movies, there is a taboo against showing breasts in public during breastfeeding.

History

The first US patent for a bra was granted in 1913 to Mary Phelps Jacob. Her invention is the most widely recognized as the predecessor to the modern bra and consequently the nursing bra. In October 1932, the S.H. Camp and Company correlated breast size and the degree they sag to letters of the alphabet, A, B, C, and D. Camp's advertising featured letter-labeled profiles of breasts in the February 1933 issue of Corset and Underwear Review. These procedures were only designed to help women with the then-standard sizes A through D up to a size 38 band size and were not intended to be used for larger-breasted women. In 1937, Warner began to feature cup sizing in its products. Other companies like the Model and Fay-Miss (renamed in 1935 as the Bali Brassiere Company) also began to offer A, B, C and D cups in the late 1930s. Catalog companies continued to use the designations Small, Medium and Large through the 1940s. In the 1930s, Dunlop chemists were able to reliably transform rubber latex into elastic thread. Man-made fibres were quickly adopted by the industry because of their easy-care properties. Since a brassiere must be laundered frequently, this was of great importance. In 1937, Warners added cup sizes (A, B, C and D) to their product line, and other manufacturers gradually followed, but Britain did not take up the American standard until the 1950s. Maidenform introduced brassieres with seamless cups in 1933, but resisted using cup sizes for its products until 1949.

Worked examples

Example 1 — a first encounter with Nursing bra

Start with the simplest possible case. Write down what Nursing bra claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nursing bra before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nursing bra ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nursing bra

In research
Nursing bra appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Nursing bra in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Nursing bra is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940s fashion, 20th-century fashion, Brassieres, so understanding it makes those chapters shorter.
In everyday life
Look for Nursing bra outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
