Twins born less than a year apart are commonly called "Irish twins," a slang term for siblings born to the same mother within a 12-month period, though the phrase has a derogatory history and some find it offensive, preferring to call them simply "closely-spaced siblings". While not medically twins, they share similar developmental stages, which can create a unique but challenging dynamic for parents.
