I have read that Isabel had at least 10 children. I only count five:
King FERNANDO II "the Catolic" of Aragon (1479-1516), Sicily and Naples (1506-16) as Ferrante III, *Sos, Zaragosa 10.5.1452, +Madrigalejo 23.1.1516; 1m: Valladolid 19.10.1469 Queen Isabel I of Castile (*22.4.1451 +26.11.1504); 2m: Blois 1505 Germaine de Foix (+1538)
G1. Juan, Pr of the Asturias, *Seville 1478, +Salamanca 1497; m.Burgos 1497 Archduchess Margareta of Austria (*Brussels 1480, +Malines 1530)

I know that Maria had a stillborn twinsister in 1482 and that Isabel miscarried a boy in 1476.
that makes 7 children>
when were the (at least) 3 children born?
