Hello Francesca,
Thank you for joining our Community forum! 😊
The Cliffs of Moher are one of the unmissable attraction on the island of Ireland and we're sure that you'll enjoy the landscape very much!
Since the tour company is not able to provide the baby seat, an option could be bringing it with you in checked luggage
or renting a seat once you're here.
Renting a car to explore the island is also a good option and would allow you to move freely around the island. What itinerary do you have in mind? Is a road trip an option for you?
I suggest that you also take a look at the
FamilyFun web page, where you can find a lot of great suggestions for families visiting the island of Ireland
Wishing you a good day!
