Could you do the course before you have bubs?
I think it will be hard for you to leave your bubba for this long. The first few weeks are really hard and you are just getting to know your baby. It ouwld be really hard if you are planning on bf too.
I am only just getting confident enough to leave my baby now and she is 13wks old. I have left her with my mum for about 3 hours, (I was at the movies with DH, 10mins away) and I still called to make sure she wasn't crying or upset and if she was I would have been home in a second!
My other suggestion would be to do the course later if you can.
I think if you have to do the course now, take your DH with you. At least she would have someone who will be with her when she's at home, someone familiar, (if you know what mean) whilst you are studying.
