Kristy - I will be going to classes. They're all evening classes too which is great for us.
I too got really, really nervous about having Madeleine when I was pregnant with her... I think it was a matter of knowing what I was in for because I had already BTDT before... and I was also worried that I wouldn't love Madeleine as much as I loved James... it feels silly to write it now but that is how I felt... I was so consumed with the love I had for James that I didn't think it possible to love another child as much. The minute she was born I realised that I loved her just as much as I loved James and I felt so much better... it was overwhelming relief too for me, probably because I was convinced I was going to be the suckiest Mum 2nd time around.
You will be amazing hun... have confidence in yourself and your body. If it helps, I loved my birth with Madeleine... because I had done it before, I knew what to expect and it was so much more calm and relaxing. I could have 10 of the births I had with Madeleine.
