Using the literature data on secular
period changes reported for the small-amplitude Cepheids (s-Cepheids) it is shown that these stars are not crossing the instability strip for the first time. After
correction of the observed pulsational chracteristics of s-Cepheids, in the diagram ”log(dP/P)100 - log P” they become indistinguishable from usual classic
Cepheids, which are supposed to have already crossed the instability strip more than (or at least) once.
