Hi...i thought I'd chime in after reading the other advice/experience because that frankly looks frightening! After having 2 children in the States, I am now having my first baby in Ireland. I am in Dublin so I can't speak about what it would be like in the country.
When I found out I was pregnant I went into a total panic because I knew NOTHING about the maternity system in Ireland and I was frankly worried about the level of care. I think that a lot depends on what your expectations are...maybe where you come from and what you're used to in your medical system. My advice would be to check out some online forums to see what hospitals are available in your area (I think www.rollercoaster.ie is a great source for baby info). And then regarding how the system is structured (private, semi-private or public), The National Maternity Hospital's website is fairly informative (it is a lot of info and I found it slightly overwhelming at first since I had NO CLUE. This is the page regarding maternity care options. And lastly, the National Maternity Hospital (aka Holles Street) offers a nice "welcome to being pregnant in Ireland" book called Maternity.
But of course as with like most things in Ireland....you will get the most information via word of mouth.
I am confident after meeting with midwives, GP and consultant that the level of medical care I am receiving is as good as I would have received in the States. That being said, updated facilities, bedside manner and any hope of hand-holding through this process from all the staff I have so far encountered is laughably nonexistent thus far. But that has been every medical professional I've encountered in the 3 years being here....from what I understand, the priority here is on your physiological health and that alone. As long as you understand these differences in the system going into it, you won't be shocked when you're waiting 2 hours for an appointment and are herded like cattle to see the consultants.
One other point that is important to note is that the Catholic roots and influence is very apparent in the maternity system. They simply don't check for abnormalities during the first trimester because in this system, you have no choice in the matter (as you might have in other countries). Nor will the hospitals consult about anything resembling a "choice". So far I am lucky to not have to encounter this aspect of the maternity system, but I have heard many a horror story. Again....this isn't so much about the level of care - it is more about the priorities and ethos of care system. Some might say it's not better or worse, but just different.
Hope you find this helpful.
