Yes, they all do. My youngest got 1 before he was 6 weeks old in order to go to a wedding in Eire....
you don't actually need a passport to go between uk and ireland, it is a common travel area, like going from london to glasgow.
but some airlines require photo i.d. for security reasons.
i think it would be the same if you flew from london to glasgow.
Before COVID-19 we flew to Dublin from London City airport and Edinburgh from Stanstead Airport, passports were required on both occasions.
