Researchers call for greater attention to be paid to ear infections

While ear infections are a common childhood experience, a new study has suggested that parents and educators should take them seriously in order to protect children’s language development.

Each ear infection, the University of Florida (UF) researchers argue, can potentially impair hearing with fluid building up behind the eardrum. Repeated, temporary hearing loss can lead to deficits in auditory processing and language development in children years later.

“Ear infections are so common that we tend to dismiss them as having no long-term effect. We should take all ear infections seriously,” lead researcher Professor Susan Nittrouer explained.

“Parents should be aware that their child may have some middle ear fluid without it being painful and work with their doctor to monitor their child closely.”

In building the research the UF team studied the auditory processing and language development of 117 children from ages 5 to 10 years both with and without a history of chronic ear infections in early childhood. On average, children with several ear infections before three years of age had smaller vocabularies and a harder time matching similar sounding words than children with few or no ear infections. They also had difficulty detecting changes in sounds, a sign of problems in their brain’s auditory processing centers.

Given that as children go through school the language they need to use becomes more complex, researchers believe that parents, physicians, and speech pathologists need to continue monitoring children long after preschool, noting that some language deficits may only reveal themselves in later grades.

“As children go through school, the language they’re required to use becomes more complex,” Professor Nittrouer said.

The findings were published in the International Journal of Pediatric Otorhinolaryngology and may be accessed here.

Keeping children safe with one simple lesson

Water safety remains at the forefront of national concern, as drowning continues to be the leading cause of accidental death for children aged 0-4.

Ecological identity: a new lens on an age-old practice

The journey to embed ecological identity is a personal one, as identity sits close to one’s heart and is shaped from our own foundational years. For myself, it was founded in warm summer afternoons playing in the rockpools along the beaches in Sydney, discovering the names of all the little creatures that lurked there, including the starfish that suctioned to my curious fingertips.

What Can Australia Learn from Ontario’s Child Care Ratios?

As workforce pressures continue to shape early childhood education and care (ECEC) policy discussions in Australia, international comparisons provide useful perspectives. Canada’s approach, particularly in Ontario, offers a case study in how educator-to-child ratios, maximum group sizes and qualification requirements can be legislated as an integrated framework.

Integrated school and early learning hubs linked to stronger transitions and family engagement

A new evaluation has found that integrating early learning, health and family support services within schools significantly improves access for families and strengthens outcomes for children, adding momentum to calls for expansion of integrated hubs across Victoria.

AERO reports growing uptake of evidence-based practice across schools and ECEC

The Australian Education Research Organisation (AERO) has reported increasing adoption of its evidence-based guidance across Australian schools and early childhood education and care (ECEC) settings, signalling a strengthening national focus on research-informed practice.
