There's an Irish Caravan & Camping Club which may help - have a look at www.iccc.ie
Relatives of mine have been members for years and travel round the country regularly.
There is a campsite down in Bantry my friend swears by, of course I cant think of the name of it now! Googled it!! http://www.eaglepointcamping.com/ You need to boo it well in advance though as it is very popular. The sites in Killarney are very good too - Fossa is one. This site is the online version of the book - I used to get it every year, it is very good. I am afraid I havent gone camping in a long time though. http://www.camping-ireland.ie/index.html Hope some of this helps. I cant imagine caravaning with a small baby though, you're a brave soul! (-:
