Not sure if you have booked somewhere yet?
I did my ante-natal yesterday with 2as1. We did it in Clontarf Castle in Dublin but it can also be done in Trim as this is where Susan (midwife) lives.
I found this great and learned loads would really recommend Susan's class and has a great after care also! Plus if you have health cover you can claim some of the money back!
Ours cost €190.00, it was on from 10 to 6.30 and we were provided with dinner and snacks through out the day.
This is the website http://www.2as1.ie/
, email me if you want to ask any q's
Best of luck with your pregnancy,
