Summary
Informal human milk sharing (IHMS) offers emotional benefits for mothers, but formal milk banks are seen as inaccessible. Policy reform is needed to improve safety and access to human milk for infants.
Area of Science:
- Pediatrics
- Sociology
- Public Health
Background:
- Informal human milk sharing (IHMS) is a growing infant feeding practice.
- Existing formal human milk banks (HMBs) are perceived as rigid and difficult to access.
- Understanding the experiences of IHMS participants is crucial for infant nutrition policy.
Purpose of the Study:
- To explore the experiences, practices, and psychological/emotional impacts of IHMS.
- To understand donor and recipient perspectives on IHMS in Ireland.
- To identify barriers and facilitators related to formal HMBs and IHMS.
Main Methods:
- Qualitative phase of a sequential explanatory mixed methods study.
- Fifteen participants (donors, recipients, or both) interviewed in Ireland.
- Reflexive thematic analysis used to identify key themes.
Main Results:
- IHMS participation driven by personal and contextual motivations.
- Formal HMBs perceived as invisible, rigid, and effortful.
- IHMS provided significant emotional relief for recipients and pride for donors.
- Safety navigated through informal trust networks; concealment from healthcare professionals noted.
Conclusions:
- IHMS offers substantial psychological and emotional benefits.
- Significant need for policy reform to improve formal HMB accessibility and visibility.
- Clinical frameworks are required to support healthcare professional engagement and risk mitigation in IHMS.

Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Parental Care
Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
Cloning of Dolly the Sheep
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter telomeres than other...
The Mammary Glands
The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
