RyanAir has the reputation of being one of the most stingy no-frills carriers. When flying RyanAir, passengers are advised to arrive early as the airline has a skeleton airport staff and closes its check-in and passport-verification desks early.

Also, it’s a good idea to pay for premium boarding as travelers with babies will not receive special treatment (does this sound like United?). During the flight, the babies are bothered by repeated advertisements/announcements as well as the constantly bright cabin lights and hence one should pack some earmuffs and eye-shading device as well.
