I really wouldn't count on you wanting to go when the time comes.
Can you do the course in a few months? It might be better to wait, I realise you are probably raring to go with your new business, but I would strongly advise to postpone.

1 - You just never know what kind of baby you might get! You may be lucky enough to get one that wakes every 4 hours for a feed, but you may get one that wants to feed 2 hrly, or even just a normal baby trying to adjust to life on the outside with unsettled periods. Also, you do need to give yourself time to recover - even with a great birth etc, you will find yourself happily in tracky daks and slippers for longer than you may think!!
2- From a business standpoint, the time and effort it can take to start a new business - even from home can be so easily underestimated. I can't stress this enough. I began a new business when my son was 4 months old, and continued had another daughter along the way. I was pretty successful, but even with careful planning you can't forsee everything and it ended up taking up massive amounts of my time to keep it jogging along until I could throw myself back into it.

I am in no way wanting to rain on your parade - I just think it would be incredibly hard to do both, and you may save yourself alot of grief and begin your business with a steady foundation.

Good luck with it, I wish you heaps of success - for both baby and business!
