Car Seat Rentals

Speak to them about specifics. What brand are they going to offer you? Then research the options and sizes and find out. They may call a convertible a "baby seat" but it might fit your child just fine. I would go with a harness if possible. Your DH might be better versed in driving in Ireland but I'd get all the extra protection I could for driving on narrow roads on the "wrong" side.

(We brought ours, so I don't know what rental companies offer. We found that once the seat was in baggage we were unencumbered - we used the airport trolley for transport. It was fairly easy to get it to the rental car and then we had a seat we and DD were familiar with. You can also get an adapter to make them into a stroller, FYI.)

That's about a 2.5 hr drive. I'd go with the booster seat, not knowing what you'll get with the "baby" seat.
Do your inlaws know?

(PS: have you booked your travel yet? If you fly into Shannon, you can shave about 2 hrs off of your drive...)

Yes...I vote for the booster seat too. Just wanted let you know that is my dream vacation spot....and it's still just a dream....I'm jealous. Have a nice trip!

Booster for the 3 yr old would work best I think. Usually boosters fit children 35 lbs and more. Have fun in the Emerald Isle. My husband and I vacationed there in Fall 2003 and have vowed to go back some day. We've had 3 kids since so gotta wait until they are old enough to enjoy travel so it will feel like a vacation for all. Best wishes! Midwife Mom

Booster or just put her in the seatbelt.
