Rhesus infants first began reliably to follow the direction of this gaze at the end of the early infancy period, at about 5.5 months of age.

Animal Behaviour

Chimpanzees did not reliably follow human gaze until 3 4 years; this corresponds to the latter part of the late infancy period for this species.

Animal Behaviour

However, this technology is still in its infancy period and poses various challenges towards up-scaling and widespread applications, such as such as lower hydrogen production rate (HPR), high internal resistance, complicated architecture, and expensive materials.

Renewable and Sustainable Energy Reviews

Thus, enhanced variation in gene expression at infancy period may be caused by individual fluctuation, rather than by gene types.

Plosone

If we assume that the whole blood RNA is originated from blood cells, variation of gene expression in infancy period is attributed to that of blood cells themselves.

Plosone

Social and ecological factors likely favor a prolonged infancy period where extensive exposure to maternal foraging behaviour would promote calf learning and survival post-weaning.

Our results are intended to contribute to the limited amount of literature examining this association, especially for offspring anthropometric outcomes beyond the neonatal and infancy periods.

Diabetes Care

Nutritional factors are important, including the 'double burden of malnutrition' - the relationship between malnutrition in maternal and early infancy periods and later dietary excess and lack of physical activity, leading to diabetes.

Health Research Policy and Systems

Our finding of a potential deleterious effect of higher maternal and infant iron stores on infant growth requires further exploration and suggests a cautious approach to iron supplementation during the antenatal and early infancy periods in populations with low rates of iron deficiency.

Archives of Disease in Childhood

Expert writing Tips

Best practice

When discussing technology or industries, "infancy period" serves as a strong metaphor for the trial-and-error phase of development.

Common error

Avoid using 'infancy period' as a synonym for 'childhood'. While childhood is a broad category, the "infancy period" is strictly limited to the earliest years. Furthermore, do not use redundant expressions like 'early infancy stage period' which clutter the sentence without adding meaning.

Linguistic Context

The phrase "infancy period" functions as a compound noun or a noun phrase that acts as a temporal marker. It specifies a particular segment of time within a lifespan or a project's timeline. According to Ludwig AI, the term is used to delineate specific developmental boundaries where certain biological or behavioral milestones are expected.
