With Annika at that age, there is no way I could have left her. It would have just torn me apart. Even at 7 months, I still can't imagine leaving her for 7 days. I'd go crazy!

Also, another issue you might want to think about is the bonding that occurs in the first few weeks. You really need to take the time to get to know your baby, and also for him/her to get accustomed to you. If you are going away for 7 days, and spending a lot of time and energy on trying to get a new business up and running, you might find that you are spread a bit thin, especially if you have a baby with colic or reflux, who demands a lot of attention.

That being said, it is your choice, and you have to do what you feel comfortable with. Good luck with the new baby, and congrats on the pregnancy!
