    "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 any fall from household furniture resulting in an ED visit with imaging, 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, 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). Most infants who fall never present to an ED, so the per-fall serious-injury rate in the general population is meaningfully lower than 9%. Combining Solaiman's denominator (~115 bed/sofa ED visits per 10,000 US under-5s annually, heavily concentrated in the infant year), the 4% hospitalization rate, and rough survey estimates that roughly half of parents report at least one infant furniture fall, the per-infant cumulative probability of a fall-related ED visit with a clinically significant injury sits around 1 in 100 across the 0-2 window. 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 — two to three orders of magnitude below the serious-injury rate.\n",

The multiplication gives the ~1 in 100 cumulative probability of a serious fall-related injury per US infant across the 0-2 window, 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",
