  "question": "What are the odds of serious injury when an infant falls from furniture (sofa, bed, changing table)?",
  "quick_answer": "Over a US infant's first two years, the odds of a serious injury from a fall off furniture are about 1 in 500, and among infants who do reach an emergency department after a bed fall about 9% have a significant injury. The felt probability runs well ahead of that surveillance data.\n",

    "description": "Infant furniture falls do not show up on any published fear survey, but they are the archetypal \"parenting panic\" event of the first two years. The mental image most new parents carry is a soft sofa, a turned back, a thud, and a silent second or two that plays back in memory for weeks afterwards. The fear attaches specifically to the moment of the fall rather than to the medical outcome, which is part of why the felt probability of something serious happening runs well ahead of the surveillance data. Parenting forums and pediatrician visits reliably surface this as one of the top reasons new parents call a nurse line in the first year.\n",

    "assumptions": "Likelier normally reports lifetime-US-adult probabilities, but this entry is scoped to the first two years of life for a single US infant. The headline is the per-infant probability of a \"serious\" fall injury — defined here as a fall from household furniture resulting in an ED visit with a clinically significant diagnosis (concussion, skull fracture, intracranial bleed) or hospital admission. The denominator-side anchor is Solaiman et al. (2023), who estimated 3,414,007 ED visits for bed- and sofa-related injuries among US children under 5 between 2007 and 2021, averaging 115.2 injuries per 10,000 persons annually, with infants (<1 year) hospitalized 1.58 times more often than older children and about 4% of all such visits ending in admission. The severity-side anchor is Kokulu et al. (2021), who followed 1,439 consecutive infant bed-fall presentations and found 9.4% with a \"significant injury\" (skull fracture 4.1%, intracranial hemorrhage or cerebral contusion 2.1%, the remainder other fractures or concussive findings). Working only from the two sourced anchors: Solaiman's 115.2 bed/sofa ED visits per 10,000 US under-5s per year (≈1.15% annually), compounded across the two-year window and weighted toward the infant year where the rate is highest, puts the cumulative per-child probability of a bed/sofa ED visit over 0-2 in the low single-digit percent range (roughly 2-3%). Of those ED-presenting falls, Kokulu's 9.4% carry a clinically significant injury and Solaiman's ~4% are hospitalized, so the per-infant cumulative probability of a serious fall injury lands on the order of 1 in 500 across the 0-2 window — with genuine uncertainty from 1 in 1,000 (hospitalization-only definition) up to 1 in 200. This is well below the earlier 1-in-100 figure, which could not be reproduced from either documented derivation path. Death is a separate question: unintentional fall deaths in US infants run around 1-2 per 100,000 infant-years, or roughly 1 in 50,000 across the 0-2 window — roughly two orders of magnitude below the serious-injury rate.\n",

Most infant furniture falls never result in a clinician visit at all; roughly 1.15% of US under-5s visit an ED for a bed or sofa injury in any given year (Solaiman 2023), which compounds across the 0-2 window to a cumulative bed/sofa ED-visit rate of a few percent per child; inside that already-selected pool, about 9% carry a clinically significant injury and about 4% are hospitalized (Kokulu 2021; Solaiman 2023), and among the highest- severity trauma-registry subset only around 5% score \"severe\" on the Injury Severity Scale (Chaudhary 2018). The cumulative-times-severity product puts the serious fall-injury probability on the order of 1 in 500 per US infant across the 0-2 window (uncertainty roughly 1 in 1,000 to 1 in 200), with death a separate and far rarer question (roughly 1 in 50,000 per infant). The data tracks bed/sofa/chair/changing-table falls specifically and excludes stair falls, window falls, baby-walker falls, and baby-carrier falls, each of which has its own mortality and severity profile. The entry also excludes abuse presenting as claimed accidental fall, which is a known confounder in the clinical literature and part of why ED clinicians take infant head injuries seriously even when the reported mechanism sounds benign. Red flags that ED guidance treats as reasons to seek immediate evaluation — persistent vomiting, unusual sleepiness, pupil asymmetry, seizure activity — are not reproduced here because Likelier publishes numbers, not clinical advice.\n",
