When Four-Year-Olds Can't Climb Stairs: The Collapse of Basic Child Development

Children are arriving at English primary schools unable to perform basic physical tasks that previous generations mastered before age three. A survey of 1,000 primary teachers reveals reception pupils who cannot climb staircases, lack the core strength to sit on carpet, and arrive in nappies at age four. One in four children starting school last September were not toilet-trained.

The government’s response? Set a target. They want 75% of children reaching “good development levels” by reception, up from 68%. Meanwhile, the actual trajectory moves in the opposite direction: 49% of teachers report school readiness has deteriorated over the past year.

This is what institutional failure looks like when measured in four-year-olds who cannot walk up stairs.

The Numbers That Reveal Systemic Collapse

The Health Visitor Disappearance: Government guidelines mandate five health visitor contacts during pregnancy and early years. Reality: 63% of parents received two or fewer visits. One in five parents had zero contact. The early intervention system designed to catch developmental problems has functionally ceased to exist for most families.

The Perception Gap: 90% of parents believe their child is school-ready. Teachers report one in three children are demonstrably not. This isn’t a minor discrepancy in opinion. This is evidence that parents lack either the information or the capacity to assess their children’s development against basic milestones.

The Screen Time Substitution: Teachers report children using American vocabulary (“trash,” “vacation”) absorbed from devices, while simultaneously lacking the muscle development to climb stairs or sit upright. Screen time isn’t supplementing childhood development. It’s replacing it entirely, and the trade produces children who speak like Americans but move like infants.

The Economic Pressure: 83% of teachers identify the cost of living crisis as a continuing factor. Parents working longer hours, less time for basic developmental activities, fewer resources for childcare that might fill the gap. The economic squeeze is being measured in children who arrive at school unable to turn pages in a book because they’ve only ever swiped screens.

What The Covid Excuse Is Hiding

Teachers are beginning to reject the “pandemic baby” explanation, and they’re correct to do so. The last cohort directly affected by lockdown restrictions would have started school in 2023. We’re now seeing deterioration in 2024 cohorts who experienced minimal disruption.

One senior leader states bluntly: “There’s only so long you can blame Covid for that. I’m sorry, but a lot of it comes down to parenting as well.”

This is the uncomfortable truth emerging from the data. Covid accelerated and exposed existing trends. What we’re witnessing is not pandemic aftermath, but the continuation of long-term decline in basic child-rearing capacity and investment. The pandemic simply removed the final support structures that were masking this deterioration.

The Institutional Failure Chain

Follow the collapse backwards:

Schools: Now spending reception year teaching four-year-olds skills they should have acquired at age two. Teacher time diverted from education to basic physical and social training. The government’s “early language support” programs are remedial interventions for problems that should never have developed.

Health Visiting Services: The early warning system has broken down. The professionals who should identify developmental delays and support struggling families are absent. When present, they’re stretched so thin that even the reduced guideline of five visits becomes two, or none.

Parents: Simultaneously victims and participants in this failure. Economic pressure forces longer working hours. Screen devices provide cheap, unlimited childcare. Basic developmental activities—playing, talking, physical movement—are displaced by whatever keeps children quiet and occupied.

Government: Responds to measurable decline with aspirational targets (75% school-ready!) while the actual trend moves the opposite direction. The minister announces “school-based nurseries” and “family hubs” while the fundamental support structure continues its collapse.

Each institution fails, then passes the problem to the next level. Parents struggle, health visitors don’t visit, children reach schools unprepared, teachers must compensate, government sets targets everyone knows are fantasy.

What This Reveals About How Things Actually Work Now

The survey data exposes a society that has lost the capacity for basic intergenerational transmission of developmental knowledge and practice. Previous generations somehow managed to toilet-train children and teach them to climb stairs without government programs, early intervention specialists, or formal school readiness initiatives.

What changed? Multiple systems failed simultaneously:

Economic: Parents need two incomes to maintain living standards that one income previously provided. Time poverty replaces material poverty for many families. For others, both forms of poverty operate together.

Social: Extended family networks that provided childcare knowledge and support have fragmented. Community resources that filled gaps have closed or been defunded. Parents are more isolated, with less access to informal knowledge transfer.

Technological: Screens provide infinite, effortless engagement. They’re cheaper than childcare, more reliable than extended family, less exhausting than active parenting. The developmental cost only becomes visible when children reach school age.

Institutional: Support systems designed to catch problems early have been hollowed out through years of incremental cuts and increasing demand. Health visitors see fewer families. Early years services reach fewer children. Problems compound until they become visible at school entry.

The Reality Check

Only 44% of parents think children should know how to turn pages in a book before starting school. Think about that statistic. Most parents don’t expect their four-year-old to understand that books have pages you turn, rather than screens you swipe.

This isn’t ignorance. This is adaptation to the actual conditions of contemporary British child-rearing. When screens are the primary childhood experience, expecting book-handling skills becomes unrealistic.

But here’s what makes this a decline story rather than simply a change story: The children still need to climb stairs. They still need core strength to sit. They still need to develop gross and fine motor skills. They still need language acquisition beyond passive screen watching.

The physiological requirements of human development haven’t changed. Britain’s capacity to meet them has.

The Trajectory

The government wants 75% of children school-ready. The trend is moving backwards. Teachers report deterioration. The support systems continue their degradation. Economic pressures intensify.

This is how institutional decline compounds. Each year’s reception class arrives less prepared than the previous year. Each cohort of teachers spends more time on basic development and less on education. Each generation of parents has less support, less knowledge, and less time.

The minister’s response—“continued investment in family hubs and start for life programmes”—is aspirational language describing programs that will be implemented inadequately, funded insufficiently, and unable to reverse trends driven by fundamental economic and social changes.

What This Actually Means

When a wealthy developed nation produces four-year-olds who cannot climb staircases, something has broken at a foundational level. This isn’t policy failure. This is the erosion of basic societal capacity to raise children competently.

The statistics from this survey will produce concerned statements from officials, additional initiatives with promising names, and another round of targets that won’t be met. Meanwhile, next September’s reception class will likely arrive in worse condition than this year’s, and teachers will again spend months remediating problems that shouldn’t exist.

Britain once had the wealth, social structure, and institutional capacity to ensure children reached school with basic developmental milestones achieved. That capability is now visibly failing, and the failure is accelerating.

The children who cannot climb stairs today will be the teenagers who cannot meet employers’ basic expectations tomorrow, and the adults struggling with problems that trace back to failures in their first four years the day after that.

This is what decline looks like when measured in the most basic metric imaginable: Can our four-year-olds walk up stairs? Increasingly, the answer is no, and nobody with the power to change this trajectory appears capable of doing so.
